This thing holds your solder. It has a few special features, including a front mounted solder winder to store dispensed solder and an integrated wall mounting system. Springs can be added to apply friction and prevent excess solder from being dispensed. Compatible with Kester leaded and unleaded 1 lb spools and possibly with others.
If there is interest I'll make an optimized version for sale. This version uses way too much plastic and I don't have time right now to optimize the design.
