Spool holsters

This is a moveable holster. The idea is for the user to nail it to the wall slightly above and behind the 3D printer.
The way it works is the user will nail the core and the wall lock (a little lower) behind the 3D printer on the wall. You then slide the spool onto the ends of the spinners. You then screw the screw stop onto the screw and then screw the screw into the top of the cylinder (finger tight). Repeat for all spools, or until out of holsters.
Then let the desired holster spin to the bottom.
Insert the stopper into the wall lock so that the spinner core won't spin anymore.
Lock that with the lock.
Connect your filament to the printer and you are ready to print.
