Summary

This is a spool holder to use vertically. It requires mounting to a vertical surface and spins onf two 608 bearings. The spool-holder is removable and sits in the base using a key system so that one can change it out depending on the size of the filament spool being used.

Designed for use with the I.S.A.A.C. 3-D printer shell (http://www.thingiverse.com/thing:334685)

Instructions

1.) print all parts + two 608 bearings, four 1/4' bolts, two M3 screws and some M8 threaded rod

2.) Place bearings in the two bearing holes in the mount and Attach the mount to the back of the vertical surface using four 1/4' bolts, facing away from your printer.

3.) place the mount cap on the mount and secure with two M3 screws. Now yiou should be able to place the M8 rod in the mount. it should rotate freely and not fall backwards due to the presence of the mount cap.

4.)Screw the Spoolholder base onto the threaded rod so that is is approx 1/2 cm from the vertical surface. The snug fit on the threads should allow it to spin on the bearings and not move about the threaded rod.

5.) finally, screw the spoolholder down the threaded rod towards the spoolholder base. When they are close, fit the triangular protrusion on the spoolholder into the groove in the spoolholder base. This should secure the two pieces into the same rotation.

6.) to change the spool holder simply unscrew it from the threaded rod and screw on a differently sized holder.
