This is a tool I Created with a few required parts… Some 5mm Carbon Fiber Rod or anything like it that you can cut 2 pieces from one is 20mm and the other about 130mm.
2 M3x4mm Threaded Heat Inserts
2 M3x14mm Screws
1 M3 Locknut
Some m3 washers
A spring that fits…
… I think that's it…
Some notes on assembly.: the bolt on the plunger IS supposed to lock the long carbon fiber rod into that piece but NOT tighten on the top completely, adjust with screw size or washers, etc. You also don't want too much play there… Mine didn't need it.
CAD included… Have at it…
m0nkee did…. you do?
