MPMD Heated Bed Hole Cover

thingiverse

The opening at the base of the MPMD allows air from the fan to circulate and cool down the heated bed. I initially covered it with a piece of cardboard, but I wanted something more efficient. So, keeping with my magnet theme, I created a magnetic cover that uses three 10mm neodymium magnets to secure it against the base. Edit: I've added an alternative design using 12mm magnets for those who prefer them. However, please note that these are actually 12.25mm in size and may not fit your printer if it's not calibrated properly, depending on the actual magnet size and any discrepancies in your printer's calibration. 13/01/2020 I've also added a new version using 13mm magnets for those whose 12mm magnets are slightly larger than expected, measuring 13.25mm in reality. You may need to use glue to secure these magnets in place.
