Smooth Spin Roller Spool Holder

This redesigned spool holder significantly enhances the printing of soft TPU filaments down to 75A shore hardness. After gathering valuable feedback from the community, I streamlined the design to use only (2) 608zz bearings, eliminating the need for additional washers or hardware (other than the original mounting bolts). While I appreciate the many creative spool holder relocation ideas, my primary goal was to keep the filament path short and reduce friction to improve TPE printing. Assembly Notes:Printing the Roller: The roller prints vertically with a small support in the bearing channel. To remove the support, insert a pin into the opposite end of the roller and gently snap it out.Inserting the Bearings: Press the bearings into each end of the roller.Final Assembly: Insert the pin from the back of the holder (mounting side) through the roller until it is fully seated in the holder body. Ensure the larger end of the pin is flush with the back of the holder.Mounting the Holder: Final
