Keypad Matrix 12mm tac switch matrix

thingiverse

This is a 4x4 keypad matrix cage for 12mm tact switches with keycaps available on AliExpress. The tact switches are very inexpensive and this little matrix keyswitch cage keeps everything straight. It works well. I was just going to glue it to the PC board, but a buddy suggested I add a flange and screw holes to be secured to the PC board... so I did. But because it prints upside down, one must use supports for the countersunk screw area. I also added a taller key cage so the keycaps just barely poke up, very nice look, and no holes as I think it can be glued down to the PC board easily.... I may add a taller one with holes.

I printed this with the settings: Rafts: Yes Supports: No Resolution: 200 microns Infill: 15% Notes: Printed up real nice on my Makerbot Replicator 2... Printed upside down on a raft, but if printed in ABS on a heated glass plate, I would not do a raft.
