Another Screw Spool Holder (No Bearings!)

Hi everyone
This is a Screw spool Holder, and I'll tell you why it's different from the other ones!
First of all, it does not require any bearing! the hole is dimensioned to realize a nearly frictionless rotation if you use a M8 threaded rod as shaft (like many default Spool Holders).
Then, you can mount spools with a maximum of 90 mm hole diameter (other designs only get to 60 mm diameter).
I'm publishing two versions, one is 70mm and the other one 100 mm long, for larger spools.
If you like my designs and are interested in my work, you can follow me on IG at https://www.instagram.com/engineli_3d/ or look for me as engineli_3d.
