Lazy-Tongs Piano Bottle Caddy
Created today
Description
A pantograph-style drink arm in the spirit of a vintage lazy-tongs: a hooked clip straddles the top of a piano's music desk, and a three-unit scissor mechanism unfolds backward to carry a bottle cup. The cup sits inside a wide, rimmed drip tray, so condensation stays off the keys and cabinet.
The arm folds flat for storage and stretches out for use. Pivots are print-in-place pins, and the two end joints ride in slots so the arms can open and close.
Design notes
- Cup bore is 76 mm, sized for a standard 33.8 fl oz (1 L) water bottle; cup wall is 85 mm tall.
- Drip tray is 96 mm across with a 12 mm rim and sits flush with the arm plane.
- Clip slot fits a music desk about 13 mm thick; adjust the thickness value to suit your piano.
- Three colored regions: desk clip, scissor arms, cup and tray.
- Shown in a partly extended pose; the opening angle can be changed to show it folded or fully reached.
- Best printed as shown, with 0.4 mm clearances at the pivots. Support is only needed under the clip hook.
- A full bottle is a cantilever load, so keep the arm short for heavier bottles.

Pi 3 case
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.
Reactor Core Echo Stand
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.
Micro Print-in-Place Joystick
This is a miniature print-in-place joystick that functions as a tactile desk toy. The internal geometry has been rebuilt to ensure the ball joint prints cleanly without supports or mid-air extrusion failures.
XIAO ESP32-S3 Chatbot Shell
Boîtier compact conçu pour intégrer une carte Seeed Studio XIAO ESP32-S3 Sense avec caméra, un écran TFT de 1,54" en façade et un haut-parleur plat (3525). L'ensemble se ferme via un tiroir coulissant en sous-face. Vérifications de montage : L'écran s'insère par l'intérieur (espace pour PCB de 32x43,7 mm). La carte XIAO repose sur une butée interne située à 43,7 mm du fond, avec une profondeur d'appui de 15 mm. La caméra pointe par le trou carré de 10 mm en façade. L'accès USB-C sort par le haut. Le haut-parleur 3525 s'encastre à fleur par l'extérieur du toit.
Modular Hexagon Phone Stand
A modern, modular phone stand built around a pure hexagonal base. The design allows multiple units to link together sideways via a built-in tab and slot system, perfect for keeping a row of devices organized on a desk or creating an expanding charging station. Design Highlights: 70-Degree Rest: The back support leans back comfortably for viewing notifications or media. Cable Management: A central pass-through routes your charging cable securely out the bottom via hidden channels. Print-in-Place Linkage: Built-in puzzle-piece connections require no extra hardware to link modules. Split Front Lip: Keeps the device firmly seated while leaving the center clear for downward cable runs.
Airpods clip
A compact, single-piece dual clip designed to snap onto the stems of AirPods Pro, holding the pair securely together without the charging case. The inner bores feature flared entries at the top and bottom to guide the stems in smoothly, while the front openings are angled to flex just enough to let the earbuds snap in and out laterally. The design prints flat without supports and relies on the natural stiffness of the filament to grip the smooth plastic of the stems. Remix Hooks This geometry is essentially a tension spring—the fit relies on your printer's tolerances and the material you choose. Opening Gap (Currently 4.8 mm): If PLA snaps when inserting the earbuds, widen the inner points of the front slot. Inner Diameter (Currently 6.4 mm): Sized for a snug friction fit on the Pro stems. Dial this up slightly if using a very rigid material, or down if you want a tighter lock. Bridge Thickness (Currently 4.5 mm): Widen this if you want to attach a lanyard loop or carabiner hole to the center.
