Description

Geared tilting tablet stand for the Doogee U11, laid out as 14 separate flat pieces for printing and assembled by hand after printing. A knob on a drive shaft turns two 30-tooth gears that mesh with 15-tooth gears on the cradle, so a small knob twist tilts the cradle forward or back.

Pieces

  • Base plate: 1
  • Side plates: 2, with tabs that drop into slots in the base
  • Tablet cradle: 1
  • 15-tooth cradle gears: 2, peg into the cradle ends
  • 30-tooth drive gears: 2, keyed to the drive shaft
  • Knob: 1
  • Axle: 1, 8 mm round
  • Drive shaft: 1, D-profile
  • Friction-fit caps: 3

Print notes

  • Every piece is laid flat on the build plate with no overlap.
  • Gear pegs face up and the shaft flat faces down, so no supports are needed for the main bodies.
  • Clearances are about 0.2-0.4 mm; adjust for your printer.
  • Gear mesh and fit are untested; friction alone holds the tilt angle.

Modular Voice Assistant Enclosure with Rotating Desk Dock

Modular Voice Assistant Enclosure with Rotating Desk Dock

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.
