WARNING: TIGHT TOLERANCES

A simple drawer i made for in my ender 3/pro/v2. I replaced it for my V2 drawer.

Drawer can hold:

1x Raspberry pi, installed in a sliding carriage

2x LM2596 buck converter

1x Relay (dont know exact size/serial number)

1x 40mm fan on front, can be installed with m3 self tapping screws but hot glue is recommended (must shave off a corner)

It has a small gap in the back to allow for cable passthrough, i cut off the small tab on the bottom of the printer to allow cable passthough.

Pictures of printed parts and installed in my printer will be uploaded soon.

Assembly Guide:

Install the raspberry pi on the slider-case, not sure which models fit on it, i used a raspberry pi 3b+ (i used m3 self tapping screws)

install all the smaller components (relay/buck converter) (tip: solder the wires first, it might be hard to reach some terminals after installing) ( also used m3 self tapping screws)

slide pi in the case from the front, usually the friction fit is good enough to keep it in place, else the cables will

connect all cables

install fan, i decided to ditch the 40mm fan and hot glue a 4010 blower inside the drawer because i had a spare one.
