That is a good idea! Never thought of that. I never use a spoolholder though. My filament is too curly and too brittle.
I made a similar one. If you don't have any bearings laying around then a simple printed roller on a smooth shaft will also work just fine. I used steel rod from a paint bucket handle. Was a tight fit so no need for any caps on the end to keep the shaft from falling out. A little oil on it and it spun nicely.
When scaling for a standard makerbot spool (75mm width) some nasty overhang is generated because the circles at the top and bottom go under the raised portion. I should crack open the SCAD to fix it but that's just too much effort.

The .STL file is for 86mm wide spools with a diameter of 160mm. If your spool has another size, use the .SCAD file instead and adjust to your needs.

Things you need:

4x bolt 8mm 4x nut 8mm 8x washer 8mm(inner diameter) 4x Bearings 22mm (608-ZZ)

(Tested!.)
