Ikea Skadis Spool Rollers

#WARNING#Apparently there are 2 types of IKEA skadis, mine has hole width of 5mm and the supports are designed for 5mm, measure your skadis hole size and if 4mm just resize the supports to 4mm. I recently built a BMCU (open source AMS) and to complete the system i needed some roll supports that are easy to install, easy to replace the spool, expandable, easy and fast to print, robust and can be used both to store and to feed the BMCU. Since i couldn't find any spool support to attach to Skadis with properly designed rollers, i made my own. Boost MeHello ! if you like or find this useful, it took quite some iterations and tests to get it right. So if you will, please boost me! It is free and motivates me to design more stuff. Thank you ! You need 4 608 Bearings for each spool, but you can print them if not available. Tolerances are a bit tight because it needs to locked together, you might need to use a point of glue to stick the pins to the rolls.
