This is my new submission for the SMuFF project.

This new case has got a bit more room for some of the features I've added recently, of which a 4 channel relay board for the Shared Stepper feature is one.

It has got space for up to two StepDown converters. One at least is used as the +5V (or +6V / +7V - whatever you need) power source for the servo(s) on the Servo Variants, because the SKR mini +5V rail isn't beefy enough to drive the servo(s) directly. The 2nd StepDown converter is optional and is not needed yet (but maybe at some point in the future).

On this case, the display cover is detachable, so you may replace it easily with a different one, say for a standard RepRap Full Graphics display.

It also has got a V-Slot rail mount, which will fit most of the 40x40 extrusions you'll find on 3D printers (i.e. Creality Ender, ...). If you'd like to use this type of mount, simply glue the V-Slot mount onto the case bottom.

Please notice, that on V5 I've moved the servo pins from the endstop connectors Y+ and Z+ to the Y-Stepper driver socket by using an adapter, documented in the pictures above. Making the adapter will take just a couple of minutes.

This move was needed in order to attach some 2.2K pull-up resistors to the servo signal lines, which, because they are pulled up to +5V, needed pins which support the "Open Drain" configuration (in order not to fry the MCU).
