Parametric/Adjusable Replicator1 Spool Holder

A ball bearing spool holder for the Replicator1 that can quickly adjust to hold different spool widths. Saves space behind the printer because the spools come off by going straight up.

I was looking for a ball bearing spool holder for the replicator1 but the only ones I could find sat on the table which was a problem with the cables in back. Also, I didn't like the way the spool could twist on the ones that used multiple bearings to handle different sizes.

I designed this one to mount on the back of the Replicator1 just like the stock holder. Also, different width spools can be used by just moving the inner support to a different slot.

The spool widths currently supported are from about 40mm wide to about 85mm wide. The supported spool widths can be changed in the OpenSCAD source code.

There is also a desktop version: http://www.thingiverse.com/thing:272532

I don't know if this also fits a Replicator2, If someone could check that I'd apreciate it.
