Version 2!

The spool holder large versions have been extended slightly to accommodate deeper spools, these are printed on edge as a single print and with supports they came out fantastic!

This is a spool holder for the ultimaker, it's sized for 30mm spools and larger.

I had trouble with the default spool holder on the back of the machine for various reasons, including it not matching spool diameters and being difficult to get spools on and off.

The two parts are attached with M2 screws. You can print the one step part, but if you do you'll need supports (I printed them seperate.)

This designs sits under the back legs of the machine and clamps between the table and the base of the machine around the support legs. It sits behind the machine and the table below both.

This design can be flipped so that you can have one of these spool holders on each side of the machine and the lower piece can be printed in a different diameter for larger spools (although the smaller diameter works very well for both.)

The default printing orientations work fine, but if you print with the orientations shown you get slightly better bed adhesion. This part comes out fairly strong, it doesn't feel as if the spool will cause any issues, plus the back of the table reinforces the downward force to lighten the load.
