Ikea Skadis Spool Roller

The original model is here https://www.printables.com/model/254310-ikea-skadis-spool-holder but with an octagonal roller. The octagonal roller would rattle the skadis board and anything else on it when it drops/rolls so i created this perfectly smooth one. Will need 2x 608 standard ball bearings. Hope this works out for some folks!
