I made a stc-1000 box that prints without supports. I made this for my heated printer enclosure, but there are many uses for these controllers. I hope this fits your needs.
The lid is attached to the base via m3 screws with nuts that are inserted into the base part. There are cable tie slots on the base where individual wires can be tied down before being sandwiched between the lid and the base.
You will need to split the stl and flip the lid part so that both parts have the ends of the box on the bed. It will then be good to go.
Rafts: No
Supports: No
Notes:
Split and flip the lid.
