Spool Holder using PTFE Tube

Light weight using least material to print a holder for spool.The spool holder intended to put inside the DIY dryer box and will also fit 4 x 1kg spool inside Ikea Samla 22l box.The 1kg spool will sit on 4 x 24mm PTFE tube for rolling, there for you should easily build it without getting ball bearing. Previously I had printed a spool holder design with ball bearing, however it does not feel much different than using PTFE / bowen tube.Important ball bearing design is slightly wider, therefore this spool holder is much efficient on space and filaments usage.Width for 2 spools is ~ 144.5mm (2 x 2 unit will fit into Samla 22l comfortablely), and single spool width is 73.2mm.I had put the 2 designs here.You will need cut the 4 pcs of OD-Ø4mm PTFE / Bowen tube x 24mm long to slot inside to the spool holder as the glider.IDØ of the tube must be IDØ2.5mm and above.
