Printing Guide

This page has commonly used settings for printing OmniBox and a printed part checklist. See the guided tour for help choosing the correct parts.

These settings are consistent for all parts.

Setting Value Note
Layer Height 0.2-0.24mm Adaptive layer heights can be used. Coarser settings have not been tested.
Perimeters (Walls) 3 Walls should be at least 1.2mm thick.
Infill 20-25% Cubic is a good tradeoff of time and durability.
Material PLA or PLA+ PETG is somewhat brittle and may take longer to print on many printers.
Nozzle Diameter 0.4mm 0.6mm should also work. If you print a case with a different nozzle size, please share your results!

This is a checklist of parts to print. Most of these parts have variations; see the guided tour for help selecting the right STL files from the git repository.
