20x40mm (2040) Small Build Compatible Top Mount Spool Holder

Design is similar to the single bracket mounting version - https://www.thingiverse.com/thing:4001842

This version will build on a 150 x 150mm printer and assembled using M3 or similar hardware to match the one piece bracket design. Currently in use on my Tevo Michelangelo printed in standard PLA; 5 outlines, 6 layers top and bottom, and 50% infill. Tighten hardware to snug and thread locker is also recommended on the bracket joining screws and nuts.

This design is to mount on a 20x40mm Aluminum extrusion end used on most small printer Z-Axis to permit filament pull on the extruder to be more horizontal than vertical. I found there to be too much slipping on my Tevo Michelangelo even with changing out the OEM plastic junk extruder with an all Aluminum MK8 with 40 tooth drive gear.

This almost zero (0) friction spool holder was part of the solution along with changing the 40 tooth drive gear to a 26 tooth on the MK8 Extruder.

CAUTION: Depending upon the printer it might be necessary to add weight to the printer to prevent tipping due to the center of gravity change with a full 1kg spool on the roller.
