Double Mosfet Box

I designed this dual mosfet enclosure to mount underneath my Lack enclosure, using these mosfet boards I bought from Amazon: https://www.amazon.com/initeq-MOSFET-Printer-Controller-Current/dp/B073QGHTZL

Of course it may fit other applications. I'm using this enclosure for my Ramps board, but it doesn't have a spot for mosfets: https://www.thingiverse.com/thing:761806

This mosfet box is sized and shape to go well with the above ramps enclosure. It has 2 openings intended to be placed up against the USB port opening, so cooling air from the ramps box passes through the mosfet box. The 0.45mm thick rectangular "windows" are there just to make printing easier (no supports and associated oozing artifacts). These windows are easily cut out with a razor after printing, or you can leave them in place (and maybe just drill holes for wires) if it fits your application better.

The lid is optional, and it snaps in place without hardware.

All parts were designed thin to save filament. The dimensions are designed for a 0.45mm printer line width (0.4mm nozzle), but other settings may work fine.

Notes:

Choose your resolution... I printed in ABS at 0.2mm, but you don't have to. Since ABS shrinks so much I had to scale down my lid 1.5mm lengthwise for a good fit. So if your lid fit is too tight, try scaling down the lid y-axis (uncheck uniform scaling in Cura).
