Ultimaker 3 extruder lever mod
This simple mod is based on oryginal Ultimaker files.
It alters extruder lever with new one, that lets You lock it in open position. Simply press lever down to lock it or pull it up to releas it back!. No more pain in your finger, just lock the lever and use both hands to whatever You need.
It has also improved guiding, so it is easier to push filament up.
How does it work?
It's simple! All You need to do is to gently push lever down to vertical postion, it will lock it self automaticly. Than you can move Your filament freely. Whe You're ready, just push it back, it will move it self to horizontal position.
