Summary This is a design for a soldering iron and solder spool holder. I've made this design free to use and documented the whole process on my Youtube channel - 3DLayerz, feel free to check it out! (Video might not be uploaded just yet but it will be there). https://www.youtube.com/channel/UCRbxcTl1xC7g_jAQ8YdLH8g It's intended to hold the handle of the iron (not the hot end :P), the spool holder can hold one large spool or many small ones. Feel free to let me know if there are changes you want to make! Print Settings Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: No Supports: No Resolution: 0.2 Infill: 10% Notes: 10% infill for the top two components, I used 100% infill for the base - using Simplify3D I did this using different processes. No supports were needed but perhaps depending on the printer it might be needed for the spindle. I printed the spindle standing straight up.
