Quick release for filament drybox

A quick release for [filament drybox for use with filament buffer, linear track rewind mechanism, or spring hub rewind mechanism](https://www.thingiverse.com/thing:3842938)

Allows the drybox to be easily removed by pressing the two tabs together on the base and sliding the drybox off the rails. Securely holds the drybox in place at any angle.

I used #8 flat head wood screws to mount the base and 8-32 x 5/8" flat head machine screws and nuts to attach the rails to the drybox.
