"El Cheapo" Magnet Base

Just a cheapskate short-term replacement for magnetic pin bases often used in single crystal crystallography. These tend to get misplaced and sometimes I need them in my travel kit, so I just made a few spares fitted for 5x5x1mm NdBFe magnets. Note: The print needs to be paused to insert the magnets. So far they fit and work well, time will tell how long they hold up.
