It's a X Carriage with single screw quick changing of extruders/tools.
- Strong LM8UU Holders
- T2.5 belt clamps (most other belt clamps should work fine)
- Mounts on each side for endstop flags or mounting a fan
- Universal adapter plate for using other extruders/tool mounts, which don't support quick changing.
The design reference and the raw plate are under CC0.
Version 2: Improved spacings
Print it with your favourite settings (I use 60% infill).
Mount the plate receiver with 4 M3 screws, washers and nuts.
Secure the LM8UUs with 4 M3 screws, washers and nuts.
