Summary

Small frame without belt pulley to extend the kossel down and create extra room for power supply and electronics.

Update: Added some more parts that I used to create a nice compartment for all the electronics.
The side panels are 4x135x240mm in size. The jigg was slipped over the sides to get the correct hole locations.
I also added the connector plate, not sure if that's useful.
Be aware that the PCB design is wrong, the GND has been swapped with another pin on the RJ45 connector.
