Tips:

Don't mind my rough print it was the last of my black until more comes in and it was a really bad roll. I usually print at 0.28 with supports for the parts that rest on the rail and where the xt60 connectors are at minimum. If using support all put blockers in the power buttons screw holes. I always forget to and they are the worst to get out.

Be sure to use a 30A relay don't cheap out and grab a 10A just because a tone of guides use them. They work fine if you are putting a relay on the power cord to the PSU as it will always be below 10A due to the higher Voltage. Where we are after the PSU the voltage drop comes with higher amperage and it is very easy for the printer to go over 10A with the power supplies often being rated for 15-20A. Well bellow the 30A relay's rating but way above 10A. A 10A relay will work for a few weeks to a month at most before it welds its self either open or closed.

When installing the case thread the screen cable through first before anything else after sliding the case onto the rail as it barely fits with another few wires but it is easily slide through with none in the way. Also install the fan last after installing the pi camera's ribbon cable as it will block the spot for installing the ribbon.

1 - Raspberry Pi 4

1 - 30x30mm Fan (comes with many pi heat sync kits)

1 - 30A Single Channel Relay

1 or 2 - Buck Converters (One for the Pi and One for all NeoPixels as their draw will put a pi into low power errors if they share)

3 - Female XT60 Connectors

2 - Male XT60 Connectors

1 - Ring or stip of NeoPixels (Optional)

1 - DHT11 (Optional)

Screws:

12 - M3*8

4 - M3* 12

2 - M3* 20

4 - M3 Nuts

Notes:

Put support blockers in the power buttons screw holes as they are a nightmare to get out. I'd also suggest not using walls around your supports as that will make cleaning out the XT60 Connectors far harder. All other supports should remove pretty easily removed.
