Spool Truck for filament dry box

This will cradle a reel type filament spool allowing smooth unreeling while printing.

This design is based on my original with reduced clearance of spool to table surface, flush bolt head hole, and integrated guide holes. As such, it is targeted to the 204mm (8") diameter reals or larger. It can accomidate almost any width.

The use of the guide rods is optional. I included the holes for them as my box was so wide and slippery that the whole truck would rotate too much. I didn't use them if it sat on a normal table top surface.

This is part of my solution for creating a filament dry box for the actively printing filament. Other parts used for solution are:
