3D Printed BC-250 Case
https://makerworld.com/en/models/2941435-bc-250-case-nexus?from=search#profileId-3323470
This case is designed for the ASRock BC-250 board and a Flex ATX power supply. Most parts should print without supports. The only parts that should need supports are the fan faceplate bracket and the handle positioning dowels.
Parts Needed
2 × Thermalright TL-8015 80mm fans
1 × 120mm fan, any brand
1 × ESGAMING 500W Flex ATX power supply
1 × 12mm latching push button
1 × 3-way PWM fan splitter
M4 × 6mm brass heat-set inserts
M4 screws
Assembly Notes
Install the M4 × 6mm brass heat-set inserts into the printed mounting points before final assembly. Use M4 screws to attach the panels, brackets, fans, and other mounted parts.
The two Thermalright TL-8015 80mm fans mount to the front fan area. The 120mm fan mounts on the side using the printed fan shroud. The fan shroud is designed to be friction fit and should provide enough clearance for most 120mm fan thicknesses.
Use the 3-way PWM fan splitter to connect the two 80mm fans and the 120mm fan to a single fan header.
The BC-250 board will need the metal bracket removed from the end of the card before it can be mounted into the case. Once removed, the board should slide into position and attach using the case mounting points.
The ESGAMING 500W Flex ATX power supply mounts inside the case and provides power for the BC-250. The 12mm latching push button is used as the power switch.
Test-fit everything before tightening the screws fully. Because this is a 3D printed case, minor sanding, trimming, or tolerance adjustments may be needed depending on your printer and material.
