This handle was designed specifically to work with my magnetic latch ( https://www.thingiverse.com/thing:2829634 ). The holes line up perfectly so the door can be sandwiched between the latch and the handle.
I highly recommend using ABS or PETG for these handles. I haven't tried PLA, but I am guessing the PLA would not take the force. The Handle has the needed rafts built into the design.
Holes fit Flat or Button M6 Screws.
