This filament holder securely hooks onto the side of your Solidoodle Press and is easily removed when needed: no velcro, tape, or extra table space required.

It is designed to be used with the printer's lid either open or propped up. I prop the lip up with my custom lid prop for the Press.

This filament holder is a new version of my old filament holder, which needed to be Velcro'd to the side of the printer, and which eventually fell off.

YOU MAY NEED TO SCALE IT UP 25.4X TO CONVERT FROM INCHES TO MM.

The left and right arms measure about 7" x 6.5". You will need to print one of each, and glue them together. I used ABS plastic glued with acetone with very good results. You will also need to print the horizontal bar that spans the arms and holds the spool; this can be printed in two parts or one.

Once it's all assembled, just hook it on and go for it!
