Mosfet Box with 30mm Fan Mount

Hi again
I have created a box to house an external mosfet found on ebay for my bed. It has a mount for a 30mm fan on the inside and is designed to mount on 2020. Here is a link to the mosfet board I used: https://www.ebay.ca/itm/3D-Printer-Heated-Bed-Power-Module-Board-High-Current-210A-MOSFET-Upgrade-RAMPS/112433582882?hash=item1a2d905322:g:HTQAAOSwjqVZNoFb.

Hope you like it!
