Spool Holder

This Is an adjustable spool holder with bearings in the wheels. The main body with rollers slide on the rails for spool width adjustability. Make sure to feed the fillament from the bottom of the roll for extra stability. All thats needed to complete this project is four 608zz (8x22x7) bearings. Uses the stock spool holder t-nuts and screws. I designed the wheels in two pieces for easier printing without supports and easier bearing insertion. Once both halves are pressed onto the bearing, you will never know its two piece. Print both the bolts and nuts at .16 with 100% infill. Also print nuts at 111% on the X and Y axis only. Put a shim on each side of the bearing on the bolt (axle).
