These are cases for the new AZSMZ Mini controller board and LCD display board. This new 32 bit controller board runs Smoothieware and was my choice for a low-cost, high-performance controller for the Kossel 2020 delta printer I built. I've designed the case to allow a 40mm fan to be mounted to provide direct cooling for the stepper motor drivers.
The holes in the cases were sized with the intention of tapping them with an M3 thread (this includes the controller board mounting holes). Lids have holes to insert M3 capscrews.
The mounting holes on the main board case were spaced to allow mounting to a standard Kossel 2020 frame design.
UPDATE: V8 is major update from previous versions. Lots of little things were tweaked. The outlet air vent was changed, and slots along the top were changed and widened to allow stepper motor and limit switch connectors to fit through (without the need to remove the connectors to thread the wires through).
Modelling was done in DesignSpark Mechanical. RSDOC file included
Support may be needed in a few places - depends on your printer.
