Description
Exposed speaker voice coils attract dust and metal particles until they grind themselves to death. This replacement dust cap seals the center of a 50mm driver without adding enough mass to ruin the high-frequency response.

What it's for A vertical, upright stand designed to hold an Echo Dot 3rd Gen while transforming it into a glowing reactor core. The custom cavity is deep enough to cover the sides of the device entirely, leaving only the top surface and the signature light ring visible from the front. A bottom channel allows the power cable to route straight down seamlessly. Dimensions Base: 120 × 100 mm footprint for vertical stability. Speaker Cavity: 101.5 mm diameter, 44 mm depth (tailor-made to enclose the puck). Overall Height: ~150 mm. Print notes Orientation: Prints best as oriented. Ensure your bridging settings are dialed in for the speaker cavity and the rear acoustics hole. Supports: You may want light supports under the bottom edge of the ring and inside the cable channel, depending on your printer's overhang capabilities. Assembly: Slide the Echo Dot in from the front, route the barrel plug up through the bottom slot, and plug it in.
Handheld-Gehäuse für eine selbstgebaute Konsole, bei dem die Kabel- und USB-Öffnung hinten nicht dauerhaft offen bleibt: Eine Klipp-Platte schließt sie und lässt sich bei Bedarf herausnehmen. Aussparung in der Rückwand: 100 × 30 mm, mittig Klipp-Platte: Außenrand 104 × 34 mm, Einsatz 99,6 × 29,6 mm, zwei Federarme mit Rastnasen, Fingermulde Innentiefe: 48 mm, Wandstärke 3 mm Display-Fenster 155 × 87 mm, Tastenlöcher 7,2 mm Druck: Schalen offen nach oben, Platte flach, ohne Stützen möglich

A bare Raspberry Pi 3 is so light that hooking up a standard HDMI cable instantly tips it off the desk. This case locks the board into a heavy enclosure and uses snap-on outer corner bumpers to give it some actual grip, so the board stays exactly where you put it. The port cutouts are oversized enough to accept real molded cables without them binding against the shell. Bed Fit: Everything is packed tightly to fit in a single run on a 180×180 mm print bed. Printing: All pieces sit flat on the plate. No supports required anywhere. Clearances: Built with a 0.4 mm gap around the board and lid joint so it slots together cleanly.
This stand pitches your 3rd Gen Echo Dot on its side to make it the glowing core of a Mark I Arc Reactor. The base features a U-shaped drop-in pocket sized perfectly for the Dot — it slides right in from the top with the cable attached, seating securely behind the front bezel. The front face frames the bottom edge of the device, turning its status light into the reactor's ring. Core Features Drop-in Dock: Fully open top channel and rear cable slot let you drop the Dot in without unplugging it. Reactor Bezel: Oversized front ring complete with ten staggered copper-style cooling coils. Embossed Text: The iconic 'PROOF THAT TONY STARK HAS A HEART' circles the top arc of the bezel. Cable Management: Rear cutout safely clears the bulky power adapter plug, and the hollowed base lets you run cables beneath.
A heavy-duty book rest that clamps directly to the edge of a desk or workbench. Built to hold reference books, manuals, or sketchpads open at a comfortable viewing angle without eating up desk space. The spine overhangs the desk slightly to keep the center of gravity stable, while a generous front lip holds pages down securely. Remix Hooks Table Clearance: The throat is set to 50mm to handle thick workbenches. Drop throat_h to 35mm if you're clamping it to standard office desks. Book Canvas Size: The backboard defaults to 180mm wide. Scale the cuboid spans up if you want to support massive hardcover atlases, or shrink them for a compact tablet holder. Tilt Angle: Defined at -15 degrees. Push it to -25 for standing desks, or pull it closer to 0 for line-level reference reading. Print tip: The main holder body should be printed on its side (rotated 90 degrees) so the C-clamp throat and backboard print without massive under-supports.
Raw development boards sliding across a desk are just waiting to short out on a stray screw or drop a jumper wire mid-compile. It’s annoying, it ruins components, and it makes moving a project impossible. This ends that. This is a clean, three-part enclosure built to lock down an ESP32 and an OLED display, keeping the wiring hidden and the desk clear. Footprint: 58.0 mm × 48.0 mm Total thickness: 34.5 mm (assembled) Display window: 30.5 mm square (designed for 1.3" OLEDs) Assembly: Uses four M3 screws driven from the back, leaving the front bezel perfectly clean. Print the three parts flat on their backs. Frosted PETG recommended if you want the board LEDs to diffuse through the case walls.
