About this 3D model
The new J-Head Hotend V5 is shorter than my Printrbot Ubis Hotend. So I made this adapter to extend the length. I haven't mounted this yet, but holding it next to my (printing) bot, it is a smidgen longer than the original. You could take a few mm off the length, but it was close enough for me. The nose needs to be a bit bigger though ;) Could possibly be used for other Hotends (?) EDIT Wrong STL - Hang on... fixed! (Trivia - if you Export as STL before Compiling, OpenSCAD exports the last file you compiled :| )
