About this 3D model

This is an adjustable spool holder that prints in 2 parts without the need for supports, screws, bolts, glue, bearings, and the best part is that this design does not have any weak points and can be printed without problem on a printer as small as 4x4. The spool holder was designed for use on a 2040 aluminum extrusion. The design lets you screw or bolt this spool holder into any surface and allows the spool to roll smoothly.
