Rat RIg Universal CNC Electronics Enclosure

The Rat Rig Universal Electronics Enclosure was designed with plenty of room to house the electronics of any CNC machine, from Rat Rig or not!
Compatible with the Rat Rig preset beginner, intermediate, and advanced electronic bundles, it features pre-drilled mounting points for popular controllers like Rodent, AXBB, Scylla, and Flexi-HAL controller boards.

Flexible mounting options
The Universal Electronics Enclosure supports all our preset electronic bundles, beginner, intermediate, and advanced with pre-drilled plates for Rodent, AXBB, Scylla, and Flexi-HAL controllers.The plates being made of aluminum, not only provide grounding for the entire enclosure but also offer flexibility for custom setups. If you prefer using your own components, the kit includes three long DIN rails, allowing you to mount your electronics with freedom and flexibility.

Safety Features
Features an IEC socket with a safety fuse, start/stop buttons, and a contactor that isolates the 220V circuit, protecting the user from high voltage and preventing automatic restart after power loss.

Cable management
AC and DC circuits are fully separated for safety, with industry standard color coded wires for ground, neutral, and live. Modular PTfix distribution blocks, also color-coded, are used to organize cables neatly.

Magnetically latched door
The Universal Electronics Enclosure includes all panels, with one featuring a magnetically latched door. It also comes with two 120mm fans and a dust filter to keep electronics cool and prevent dust buildup inside.

Printed parts

Check our github to get access to STL files for all printed parts. All files are provided in the correct orientation for printing on a standard FDM 3D printer. In general the printed parts are quite forgiving, but are also quite large. If you suffer from drafts and/or poor bed adhesion you may need to use brims/rafts for some parts to prevent warping.The following table shows the recommended print settings when printing any of the parts provided.
