Tenlog TL-D3 Pro Spoolholder

This is a low resistance top mounted (20cm x 20cm extrusion) quick release spoolholder. The spoolholder runs on an 8mm rod and uses no bearings. 8mm M5 nuts and bolts hold the mounting to the side extrusion and the 8mm M4 T nuts (and split washers) or 8mm M5 T nuts on the top. This requires no supports but a brim is advisable.
This is primarily designed for the Tenlog D3 Pro as it would be difficult to put T nuts in both top and side of the extrusion.
