3D Printing Guide

All printable parts live in the hardware/v2.0 folder of the repo.

Print settings

Setting Value
Material PETG
Layer height 0.25 mm
Infill 20–30 % (gyroid or grid)
Supports As generated by the platter project

PETG is recommended because the device sits in a window and can get warm in direct sun — PLA can soften and warp there.

How to print

Recommended — the print platter

The parts are pre‑arranged, oriented, and supported on a ready‑to‑slice platter:

Open it in PrusaSlicer (it's a 3MF project, so the layout, orientation, and supports come with it), slice, and print. If you have a different printer, just change the printer/filament profile and keep the part orientation.

Individual parts (CAD)

If you want to modify a part, re‑orient it, or print just one, the individual parts are provided as STEP CAD files in hardware/v2.0:

File Part
motor-housing-top.step / motor-housing-bottom.step Motor housing
front-plate-1.step / front-plate-2.step Front plates
back-plate.step Back plate
wall-mount.step / wall-connector.step / screw-wall-connector.step Window/sill mounts
lead-screw-gear-1.step / lead-screw-gear-2.step Lead‑screw gears
bearing-holder.step Bearing holder
internal-screw-cap.step Internal screw cap
button-big.step / button-small.step Button caps
screw-pusher.step / aligner-tool.step Assembly tools

STEP files are CAD, not print‑ready. Import them into your slicer (or CAD tool) and orient them yourself before printing — the platter project is the reference for correct orientation.

Don't want to print at all? The kit including 3D‑printed parts ships the plastics ready to assemble.
