Here are some parts that I remixed and used for my AtomX MK3 build.
The extruder is a remix of the Prusa MK3 but with the Direct Drive chopped off.
It also has a sensor for Auto Bed Leveling

My AtomX is mounted to an IKEA bamboo chopping board for stability.
I also cheated and widened the X-Carriage and printed the bed as a One-Piece.

The bed is an Aliexpress 120*120mm 12V R207, but I still need to figure out how to connect it. It has 5 wires.

• -Heat and 12v is the heating I guess
• C16, 5v, GND the thermistor. (No clue how to connect this)
