Low friction spool adapter

Low friction adapter for a generic cardboard spool supplied with a 1kg TPU spool. Background:Printing a lot of TPU using Bambu Labs P1S printing, started using softer TPU and had some feeding issues especially towards the end of the reel, as the smaller the reel becomes the more the reel has to spin as the filament is pulled off the reel.I am printing TPU direct from a Creality Pi filament dryer plus (dual).The dryer has two little rods on small bearings that spin as the filament is pulled off the reel, unfortunately it doesn't allow the reel to freely spin as easily as it could. My solution:Add a slightly larger spool with 6 x bearings allowing the spool easily spin with very little resistance. Limitations:Slightly larger - the spool is 205mm in diameter (adding a total of 5 mm to a normal cardboard spool) and 117mm wide at widest point (the centre rod/nut)It will fit easily in the dual Creality Pi fiament dryer as it sits across both sides - I drilled a small central hole in the
