Filament Joiner

For those with a 3D printer, joining filament becomes essential for utilizing short leftover pieces. While Rich's design (http://www.thingiverse.com/thing:9850) is efficient, it requires heat resistance and computer control. To tackle this issue, follow these steps: measure your soldering iron tip to determine the aluminum rod length; cut a 80mm rod, drill holes for wire stop and groove, file flat parts for heating filament ends, and mount the tip in your soldering iron at 160 degrees. Practice is key; use sandpaper for smoothing if needed. Visit http://old.snille.net/index.php?info=joiner for a detailed guide.
