Printing Guide

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

3D Printing Settings

  • Modified PLA (PLA+/PLA Pro)
  • PETG
  • Unmodified PLA

OmniBox prints best with modified PLA. Printing in PETG typically takes longer than PLA but otherwise produces good results.

Unmodified PLA (generally prints at 180-200C) is prints easily but is a rigid, weak material. Modified PLA is more flexible, among other benefits.

Note

Fan gaskets are an optional noise reducer and require TPU.

These settings are consistent for all parts but the optional fan gaskets.

Setting Value Notes
Layer Height 0.2-0.24mm Coarser settings have not been tested.
Adaptive Layer Height Optional Can improve appearance and reduce print time.
Perimeters (Walls) 1.2mm+ 3 perimeters with a 0.4mm nozzle. 1.5mm+ results in solid main body side walls.
Infill 20-25% Cubic is a good tradeoff for time and durability.
Nozzle Diameter 0.4mm, 0.6mm If you print a case with a different nozzle size, please share your results!
Support Overhang Angle >= 60 degrees This reduces print time & support material.

PETG Settings

  • Use 1.6mm walls/perimeters (1.8mm for 0.6mm nozzles).
  • If printing in a drafty room, consider a partial enclosure to help layer adhesion.

Core Component Settings

  • Supports must be on.
  • Support blockers are recommended for zip tie anchors and fastener holes.
  • Use a brim or adhesive for large parts.
  • Cantilever bed printers (e.g., Ender 5 Pro) should move heavier prints to the supported side of the bed.
