About this 3D model

This is a universal spool holder that fits any size spools and has it lay on its side which makes it easy to place and swap rolls of filament. Standard Skateboard Bearings were used, here is a link to the ones I had lying around. https://www.amazon.com/Bones-Reds-Precision-Skate-Bearings/dp/B000FDRQ1S/ref=sr_1_2?ie=UTF8&qid=1477158359&sr=8-2&keywords=bones%2Breds%2Bbearings&th=1&psc=1 https://youtu.be/xUGud6pGzDQ
