Prusa Power Supply Vent Cover

thingiverse

At 3DUPfitters, we offer a <a href="https://www.3dupfitters.com/products/prusa-acrylic-enclosure-kit">Prusa i3 MK3S enclosure</a> that many customers use for other printers. It's great to see people repurposing our products, but the enclosure comes with a cutout on the right side to supply air to the power supply. Some Prusa owners don't prioritize power supply longevity and want to push their printer's components to extreme temperatures. For these users, this handy cover seals off the PSU vent completely. However, it must be made from ABS or PETG to withstand the heat without warping. Note that our customized version shown in the picture includes a rubber grommet. This basic design is universal and does not include a hole for a grommet. This cover will fit any Prusa enclosure sold in April 2019 or later, as earlier versions had slightly larger PSU vents.
