RiiDraw Case - Compact Enclosure

This is a compact electronics enclosure designed for a RiiDraw microcontroller bridge setup. It was created as a practical case for organizing and protecting the small electronics used in a RiiDraw project.

The case includes separate top and bottom STL files, a full assembly 3MF, and a Cura project 3MF. The Cura project file is the recommended download for Cura users because it includes the intended print orientation and support/blocker setup.

Tested on: Ender3 v2 using Cura.
Recommended print setup:

Material: PLA or PETG
Nozzle: 0.4 mm
Layer height: 0.24 mm
Walls: 3
Top/bottom layers: 4
Infill: 10–15%
Supports: Required
Support placement: Touching build plate or normal supports as needed
Brim: Optional, depending on bed adhesion

Important print notes:

This case prints best with supports. The supported part prints upside down, so clean support removal matters. For best results, use support blockers around the clips, clip holes, and USB-C openings to keep those areas cleaner. This is not strictly required, but it improves the final fit and reduces cleanup.

The clip areas can also benefit from local 100% infill or a modifier mesh if your slicer supports it. This is optional, but recommended if you want stronger clips.

Known limitations:

This is a hobby electronics enclosure. It is not waterproof, not impact-rated, and not intended for high-heat, outdoor, automotive, industrial, or safety-critical use. Fit may vary slightly depending on printer calibration, filament, slicer settings, and the exact hardware used.

Compatibility note:

This is an unofficial community case designed for use with a RiiDraw-style electronics setup. It is not an official RiiDraw product and is not affiliated with the RiiDraw creator.
