Today I was making a power supply wire to work on the bot without the need to worry about batteries. I needed to solder a couple connectors. During this time my solder roll kept moving around, I was thinking I should have purchased a device to hold the roll.
Well, who needs to buy a holder when you have Shapr3D and a 3D printer. So I just created one, I will print it tomorrow. Here are a couple screenshots.
I shared the STL files here: http://www.thingiverse.com/thing:2187250
