SOLDER STAND

I would recommend printing this model at 0.2 mm layer height to get a better surface finish and to make it more easy to clip in the holder for the solder wire. 

I used two 608Z ball bearings. 

Print with no supports.

You will need to print 2x solder_roll_adapter.

The diameter of the solder spool is 11mm and for the ball bearing it's 8mm. This may varies in your special case so you may have to scale the solder_roll_adapters for your specific case.
