Printing Guide
This page has tips and common settings for printing OmniBox.
Recommended Materials
A complete OmniBox requires approximately 1.5kg of material.
Modified PLA
OmniBox prints best with modified PLA, usually called PLA+ or PLA Pro. Modified PLA is typically advertised as offering higher impact resistance, heat resistance, or other superior properties to unmodified PLA.
If your PLA filament mentions having additives, it's almost certainly modified.
PETG
Printing in PETG requires more tuning than PLA but offers a higher heat resistance.
Unmodified PLA
Sometimes called Basic PLA or just PLA, unmodified PLA prints easily but is a rigid and weak material. If a manufacturer sells multiple PLA lines, the cheapest is sometimes unmodified.
Note: Fan Gaskets
Fan gaskets are an optional noise reducer and require TPU.
Tuning
It's worthwhile to do some preventative maintenace before putting your printer through printing an OmniBox. Have you tensioned your belts or cleaned out the extruder gears recently? A little maintenance now can save a lot of heartache later.
Likewise, it's a good idea to dial in the settings for the (usually two) filament colors you plan to use. If you need a tuning guide, Ellis' Print Tuning Guide is widely considered the best.
3D Print Settings
These settings are consistent for all parts except the TPU fan gaskets.
| Setting | Value | Notes |
|---|---|---|
| Layer Height | 0.16-0.25mm | Coarser settings have not been tested. |
| Adaptive Layer Height | Optional | Can improve appearance and reduce print time. |
| Perimeters (Walls) | See below | Correct value depends on material. |
| 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! |
| Supports | Off | Supports are built-in starting with v0.9.11. |
Material-Specific Settings
PLA
Print with 1.2mm or thicker walls (3 perimeters with a 0.4mm nozzle). 1.5mm+ results in solid Main Body side walls.
PETG
Use 1.6mm walls/perimeters (1.8mm for 0.6mm nozzles).
Support Settings
- Leave supports off for all parts.
- The Main Body and Base both contain built-in supports where needed.
General Tips
- For large parts (e.g., the rear main body) use a brim, adhesive, or both.
- Cantilever bed printers (where the bed is supported by a single Z stepper; e.g., Ender 5 Pro) should move heavier prints to the supported side of the bed.
- If printing in a drafty room, consider a partial enclosure to help layer adhesion.
- Long lids will fit on 220x220mm beds if printed without a skirt or brim.
