Description
A chunky, freestanding name plate designed specifically for a classroom desk. Featuring bold, easy-to-read lettering positioned on a stable plinth, it satisfies teacher requests for desk markers while adding a playful touch to a student's workspace.
Perfect for the start of the school year when teachers ask for a designated desk name plate. The thick letters and wide base mean it stands up securely on its own and survives the chaos of a classroom environment. It is designed to be an easy, foolproof file to hand off to a family member with a 3D printer when you need a reliable result fast.

A two-part enclosure system for a modular AI voice assistant: a pocket-sized "Brain" that works on its own, and a desktop station that docks it, swivels a full 360° and carries a 3.5-inch touchscreen behind a removable bezel. Both halves share the same matte-black design language — rounded corners, smooth surfaces and 2–2.5 mm walls — and print as eight separate pieces. What it's for Brain — houses an ESP32-S3 N16R8 board, an INMP441 I2S microphone, a MAX98357A amplifier and a 20 mm speaker behind a grille. A circular LED ring glows through a 0.8 mm front skin for listening, thinking and speaking states; there is no display of its own. A USB-C port sits on the short end, and the unit runs standalone once lifted off the dock. Desk station — a weighted base with a bolted lid carries a swivel plate and the dock tower. The Brain drops into the tower pocket from above with its face still visible, and a USB-C plug cradle in the pocket floor lines up with the port. Display — the tower front takes a standard 98 × 56 mm touchscreen module in landscape, held on four M2 bosses and framed by a bezel that drops into a recess in the front face. Removing four screws frees the display for replacement, and a flat-cable slot below the opening routes the ribbon into the cavity. Rotation — the swivel plate's hollow stem passes through the lid, a retaining ring screws on underneath, and the cable runs down the centre of the stem, so the tower turns 360° without twisting the lead. Dimensions Brain: 85 × 50 × 25 mm overall, with a snap-fit rear cover. Desk base: 120 × 120 mm with 22 mm corner radii; base, lid and swivel plate stack to 65 mm. Dock tower: 104 × 40 × 119 mm, docking the Brain vertically above the display section. It overhangs the 100 mm swivel plate slightly at the front and rear corners. Display opening: 84 × 54 mm, with mounting bosses behind the wall at ±46 × ±25 mm and M2 pilot holes; bezel 100 × 60 × 2.5 mm. Walls: 2–2.5 mm throughout hollow cavities. Print notes Print the Brain shell face-down for a smooth front skin; the LED ring, microphone port and speaker grille all sit in that face. The rear cover snaps on with two bump-and-groove pairs along the long sides; pads on its inside hold the ESP32 down. The tower's internal floor and the display window bridge wide spans, so expect a little support in the dock tower only. Everything else is oriented to print without it. Print the bezel flat; it is a thin frame and needs no supports. PLA or PETG both work; four rubber-foot recesses under the base are worth filling. All eight pieces — Brain shell, rear cover, desk base, base lid, swivel plate, retaining ring, dock tower and display bezel — are separate. The lid bolts on at four corners and the display bezel screws in from the front. Compatibility The display bosses use M2 pilot holes; check your module's hole spacing before driving screws, since pinouts vary between boards. The dock pocket is sized for the Brain as drawn — if you change the Brain's shell, adjust the pocket in step. Remix ideas Lean the dock back a few degrees for a more natural viewing angle if you can accept the extra support. Swap the removable bezel for a blank panel or a vent if your build has no screen. Scale the docking pocket to fit a different companion device while keeping the same swivel mechanism.
A five-pocket desk organizer for a 150 × 110 × 120 mm footprint, with "ReplixHD" embossed on a raised front plate. Fit Scissors slot: 40 × 100 mm, 105 mm deep. Pen slot: 40 × 52 mm, 100 mm deep. Pencil slot: 55 × 52 mm, 90 mm deep. Marker slot: 40 × 45 mm, 70 mm deep. Small slot for clips and erasers: 55 × 45 mm, 40 mm deep. Walls are 2.5 mm and dividers are 2.5 mm. The pockets' floors sit above the 3 mm base, which is thicker where the pockets are shallower. Check before printing Pen and pencil slots are about 40–55 mm across, so measure any oversized markers against that. Scissors need a handle under 40 mm wide. Print notes One solid body, with no supports needed. The side ridges are sloped at about 60° so they print cleanly. It does not fit anything that needs a closed lid or a drawer.
Octobay turns a five-bay stack of half-height 5.25" slots into room for eight 3.5" drives, and adds a 25 mm front cage that carries two 92 mm fans. The outer side faces take M3 heat-set inserts, so the whole cage screws into the case's 5.25" rails instead of resting on them. Everything is one printed part: the drive stack, the side mounting blocks and the fan cage print as a single body. Because the fans close off the front, drives now load from the back. The fan cavity behind the grille is hollow, so air still passes through to the drive stack. Dimensions Overall: 145 mm wide × 197.5 mm deep × 205.5 mm tall Fits: five half-height 5.25" bays Holds: eight 3.5" drives, stacked vertically Drive channel: 102.6 mm wide — 1 mm of play around a 101.6 mm drive Mounting 20 insert holes, 10 per side, for M3 heat-set inserts — 4.2 mm across and 6 mm deep Two insert holes per bay, at 41.3 and 117.5 mm from the front, 6.35 mm above each bay floor Solid blocks sit behind each hole to give the inserts something to bite into Three M3 screw holes per side per drive, at 14, 76.6 and 117.6 mm from the front Cross ribs sit clear of the screw holes so a screwdriver can reach every fastener Fan cage Two 92 mm fans, stacked vertically on the 25 mm front section 88 mm fan openings with 4.4 mm screw holes on the standard 82.5 mm square pattern Hollow cavity behind the fans feeds air to the drive channels Print notes Drive channels are open at the back, top and bottom, and the gaps between the inner and outer side walls are open for cable routing. Screw and insert positions and the 205.5 mm height follow common 5.25" bay standards; they have not been checked against a specific case, so measure your bay rails and drives before printing.

A fidget slider that prints already assembled, so there is no loose weight to lose and nothing to glue. The slider is captured in an enclosed dovetail track and cannot fall out. It runs 40 mm end to end and clicks at each stop instead of rolling freely. What it does Slides back and forth along a closed track in an 80 x 25 mm body. A small bump on the track floor at each end of travel drops into a dimple under the slider and gives the click. The dovetail profile holds the slider down, so it cannot lift out of the rails. Numbers that matter Body: 80 x 25 x 11 mm, with the slider top reaching 14 mm. Slider: 20 mm long, 18 mm wide cap. Travel: 40 mm. Clearance between slider and track: 0.4 mm per side. This is what lets it move after printing. Click bump: about 0.6 mm of interference against the 0.4 mm gap. Reduce the bump height if it feels too stiff. Printing Print flat, body base down, with no supports needed inside the track. Use a well-tuned printer. A 0.4 mm gap fuses easily if the flow is too high. After printing, work the slider back and forth a few times to break any thin bridging between the slider and the rails. Two colours show as separate parts in the preview, but the print is one job.

Bisel frontal para una pantalla táctil de 10,1 pulgadas (tipo Raspberry Pi Touch Display 2), en horizontal, inclinado 30° respecto a la horizontal y montado sobre una base de bloque. El bisel tiene sección en L: una placa frontal de 1,6 mm con la ventana de visión y una pared perimetral de 7 mm que baja hacia atrás, con la parte trasera abierta para alojar el panel. La ventana es recta, sin chaflán, y está descentrada respecto al contorno exterior. Detrás de la zona de la pantalla va un soporte para atornillar la Raspberry Pi, bajado 4 mm hacia la placa frontal, de modo que los postes apoyan en la cara interior de la placa; la barra del soporte tiene una abertura de 40 × 30 mm y la pared lateral +X tiene una ranura abierta de 60 × 20 mm para USB y Ethernet. Los cuatro agujeros guía de los postes siguen abiertos. El modelo consta de dos volúmenes, Bisel y Base. El bisel es una pieza entera, sin recortar contra el bloque, y va hundido en la base: su borde inferior queda por debajo de la cara superior del bloque. La base tiene un hueco posterior con la forma exterior del bisel, de modo que la pieza encaja dentro, y conserva la abertura frontal para el paso de los cables. Cotas del bisel Exterior: 265,05 × 183,75 mm, con 40 mm de profundidad total y esquinas exteriores redondeadas (~3,5 mm); borde frontal redondeado (~1,5 mm). Placa frontal: 1,6 mm de grosor; pared perimetral de 7 mm. Ventana de visión: 220,5 × 138,65 mm, recta, sin chaflán y descentrada. Cavidad interior para la pantalla: 251,05 × 169,75 mm. Base e inclinación Bloque de 365 × 100 mm de planta y 50 mm de alto, unos 5 cm más ancho por cada lado que el bisel. Inclinación del bisel: 30° respecto a la horizontal. La base conserva un hueco posterior con la forma del cuerpo del bisel; solo queda maciza alrededor de ese hueco. Abertura para cables de la controladora en la cara frontal de la base: rectángulo de 180 × 37 mm, centrado en horizontal, que arranca a 6 mm de la cara inferior y penetra 9 mm en el bloque. Medidas en la placa de impresión: Bisel 265 × 177,1 × 126 mm; Base 365 × 100 × 50 mm. Comprueba que ambas caben en el volumen de impresión disponible. Verifica en la vista previa que la cara frontal y la ventana quedan despejadas y que el bisel encaja en el hueco de la base sin dejar escalón. Soporte de Raspberry Pi y cables Barra transversal de 3 mm, de pared a pared, situada justo detrás de la zona de la pantalla, con su cara posterior a unos 6,6–9,6 mm de la cara frontal; no llega al borde trasero. Cuatro postes de 5 mm que apoyan en la cara interior de la placa frontal, con agujero guía de 2,2 mm para tornillos M2,5 pasante hasta la placa; separación de 58 × 49 mm. La placa queda desplazada hacia +X, con centro en X=75 mm. La barra del soporte tiene una abertura de 40 × 30 mm centrada en X=75 mm. La ranura lateral para USB y Ethernet está abierta en la pared +X, de 60 × 20 mm, a la altura de la barra, y se desplaza con el soporte. El soporte se dimensionó sin un modelo concreto de Raspberry Pi: comprueba la separación de los postes y la posición de los agujeros guía antes de imprimir. Detalles interiores Cuatro torretas cilíndricas macizas de Ø8,2 mm en las esquinas interiores, con centro a ±123,25 mm en horizontal y ±82,7 mm en vertical respecto al centro del marco. Recorren la pared desde la cara interior de la placa hasta 2 mm antes del borde trasero, y quedan recortadas por el contorno exterior. Agujero pasante en cada torreta, de delante hacia atrás: apertura redonda de Ø5 mm en la cara frontal, cono de 45° que baja de Ø5 a Ø2 en 1,5 mm y tramo de Ø2 mm hasta salir abierto por detrás. Admite tornillos autorroscantes de hasta Ø2 mm. Profundidad del tramo de Ø5 mm, distinta por esquina: 5,75 mm en las dos inferiores, 4,55 mm en una superior y 3,15 mm en la otra. Canto de la pared perimetral nivelado, sin muesca ni rebaje: el borde trasero queda liso y a una sola altura en todo el perímetro. Ocho tacos de apoyo sobre la cara interior de la placa, de reparto asimétrico: dos arriba, dos abajo y dos en cada lateral. Llegan hasta 7 mm del borde trasero, de modo que con la pared de 40 mm son mucho más altos que los 2 mm del diseño de partida; mantienen esa distancia al borde trasero, no la altura. Impresión Dos volúmenes independientes: bisel y base. La pared perimetral de 7 mm se resuelve con perímetros múltiples con boquilla de 0,4 mm. Torretas y tacos llegan casi hasta el borde trasero: al imprimir con la cara frontal sobre la cama son columnas altas, conviene revisar que no vuelquen. Revisa que la barra y los postes del soporte de la Pi no interfieran con el panel y que la separación de 58 × 49 mm coincida con tu placa. La ventana coincide con la zona activa del panel (220,5 × 138,65 mm), por lo que el ajuste es ceñido; verifica las cotas antes de imprimir.
