Bambu spool holder adapter - less extruder strain

Spool holder upgrade - the purpose of this upgrade is to reduce the strain and wear of the extruder gear and motor. It allows for an easier filament flow through the PTFE tube and through the nozzle/hotend.

How to assemble: -------------------------------------------------------------

! It is important to know that you need 4 flanged ball bearings for this upgrade. You can get them off TEMU for 3-4$ or you can get them for a local hardware store (https://www.temu.com/ro-en/10pcs-mf52zz-mf62zz-mf63zz-mf74zz-mf83zz-mf84zz-to-mf148zz-miniature-flange-bearing-thin-wall-metal-shielded-flanged-bearings-g-601101431047091.html)

The ball bearings should be 14mm in outer diameter (OD) as well as 8mm in inner diameter (ID)!

First of all, put the bearings on the extruded supports and then attach the two long tubes. After that, you can either screw or glue the two base parts together (I recommend glue because it is a lot easier, but if you want you can use M3 screws - make sure that they are long enough to pass through the first small part and into the second larger one).

After doing that, you can simply put the assembly onto the printer's spool holder.

Done!
