Solder Scroll - Ergonomic, Adjustable Solder Tool

The Solder Scroll makes soldering more ergonomic by allowing you to just scroll on the pen shaped tool to add solder. By rotating the knob, the tool can be adjusted to accomodate different diameters of soldering wire (0.3 - 1.5mm). A length of soldering wire is stored on the back and can easily be refilled. All parts are easily printable without support on an FFF/FDM 3D-printer. The assembly requires no glue or metal fasteners. Update 5 Oct 2024: Several part versions have been added with additional clearence. If you experience trouble where the rollers don't roll smoothly with the default clearence, printing a version with more clearence could help. H ow to use the Solder Scroll Adjust the tension to the diameter of the solder by rotating the knob. The tension is right when the scroll wheel grips the solder. 📷 Image redacted — claim this model to add your own media Grip it like a pen in your left or right hand. 📷 Image redacted — claim this model to add your own media Add solder to your solder joint by rolling the scroll wheel towards you.

No supports are needed. Adding a brim to the Clip part was nescessary when I printed the parts. I used PLA with 0.2mm layer height and 15% infill. 📷 Image redacted — claim this model to add your own media Assembly If nescessary, remove the brim from the clip and clean up the seams on the bearing surfaces. 📷 Image redacted — claim this model to add your own media 📷 Image redacted — claim this model to add your own media Assemble the wheels on the main body. Tip: Carefully adding a bit on lubricant on the bearing surfaces will reduce the friction (I used PTFE spray). 📷 Image redacted — claim this model to add your own media 📷 Image redacted — claim this model to add your own media 📷 Image redacted — claim this model to add your own media Install the cover and add the clip. 📷 Image redacted — claim this model to add your own media 📷 Image redacted — claim this model to add your own media Loading the solder Stick the end of the solder wire into the hole on the spool and roll some wire on it. 📷 Image redacted — claim this model to add your own media 📷 Image redacted — claim this model to add your own media Feed the solder in the back of the main body until it comes out at the tip. 📷 Image redacted — claim this model to add your own media Install the spool and add the clip. 📷 Image redacted — claim this model to add your own media 📷 Image redacted — claim this model to add your own media The assembly is done!
