After adding the Ikea Lack tables to my printer, I couldn't use the spool holder that hooked onto the printer frame. This remix allows the base to screw onto the top Lack table and the floater to slide to allow for different size spools. I'm using the filament guide from http://www.thingiverse.com/thing:1740538

The fit is very tight. I didn't want it to move during printing. The bearing mounts had to be sanded down a little to get the bearings on.

The remaining parts and assembly instructions are found on the source project page: http://www.thingiverse.com/thing:1635585
