3D model description

Nozzle cleaning system used for d-bot like setup
there 2 versions. I am using 2nd one. For the first version need to find proper filament or made it from high temp silicone
1st
mbot-ncleaner-p1.stl
mbot-ncleaner-p2.stl
mbot-ncleaner-p3.stl - this part should be printed from nylon or any hi temperature material

2nd
mbot-ncleaner-p1.stl
mbot-ncleaner-p2-v2.stl - insert the nylon cable tie as cleaner

Also you need bolt m4x50 (or check you length) and m4 nut
