Summary

Motherboard Case Designed to externalize the BTT_SKR_V3 board or the creality stock board 4.2.7

I designed this because I was getting tired of getting under my printer and risking knocking my leveling out of wack by either moving screws or bumping the gantry etc.

This print requires
(5) m3x5mm thread heat inserts - to fit the original 3mm socket head screws from creality
(2) m3x8 heat insert - for lid
(2-4) m3 hammer nuts (tnuts)
(2-4) m3x10 bolts
(2) m4 bolts to mount elbow to the back of the carriage

1.5ft length of pairs 16 gauge wire (power)
extension for display adaptor

NOTE: This solution by default does not allow for the stock power wire from the power block. you will have to replace this with a longer cord

NOTE: the display cord is not long enough to reach the original position. you will either have to move the display to the left hand side or extend the display cable.

This will fit either the BTT_SKR_V3.0 OR the stock creality board.

The front panel will have to be cut out after print.

Post-Printing

Step 1

Cut out the front panel with exacto knife or box cutter

Step 2

Heat press thread into board in 5 locations

Step 3

Remove Power Supply and replace power lines with longer wire.
Make sure you remove the Y motor cord and y limit switch cord from the power casing to re route them. You will not have enough cord if you do not.

Replace power block into the chassis. Make sure you remove the old rub tape from the old cord and add that to the new cord at the location where the wire rubs the chassis.

Step 4

after removing the wires from the previous board, route them first through the elbow(if used) then through the spacer and finally into the case.

OPTIONAL: mount the case to the chassis/frame with all 4 bolts and t-nuts (hammer nuts)

Make sure you include the spacer. The case alone does not have room to clear the Z axis motor

In my case it was easier to wire up the board AFTER routing them in the case, then mount the board then use the two nuts that are left exposed to mount to the chassis
