Right side mounting for relay, 40mm fan, and slot for Pi Camera cable

thingiverse

Update: I've since printed this control box for a 2nd printer and found the additional shelf for the 40mm unnecessary and adds to the bulk within the case. Removed the shelf and the fan grill. This is a remix of the right side of the AIO electronics case. I wanted to add a slot for my pi 4 camera cable as well as remove the mount locations for the MOSFETs that I do not need. In the place of the MOSFET mounts I put a mount points for a properly rated relay as well as a shelf for a 40mm fan. My Meanwell PSU fan only is active when the PSU comes to temp but wanted to the board to be able to control airflow on a smaller scale should the need arise separate from the PSU. This is the relay I decided on and works great using gpio pin 14 on the pi 4. The Pi and relay are both powered by a buck converter. https://www.amazon.com/gp/product/B07DSZFLMQ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
