This is a Gridfinity plate for the Fixdry fillament dryer.

I've printed multiple of these silica gel gridfinity bins

I wanted a way to dry them all using my Fixdry filament dryer, so i made this baseplate.

It is not possible to use this by its own, since the thermometer in the dryer is protruding upwards.

Add either the spacer with PTFE connectors

Or the spacer without

Before adding the gridfinity plate, then it will fit. (plus you will have more space in your dryer)

Use ABS or ASA filament when printing so it does not melt in the dryer
