RatRig Toolhead V1 with Filament Cutter

***Update June 9 2025*** Revised front print to add hole for bolts that hold belt. It did not pass all the way through the top. rev A

***Update November 28, 2024*** Fixed actuator added to parts. To use this actuator you will have to modify your max allowable x stepper variable to provide for 15mm more than the standard current maximum. e.g. if 400, it would need to allow for 415. The fixed actuator will not interfere with printing on any portion of the bed. I am taking advantage of the wider travel range added for IDEX. Obviously this design is not suitable for IDEX as it is meant for multimaterial single extruder setups. It may be possible to add the cutter to IDEX, but it may not be. I have not checked nor designed for that scenario.

This is an Alpha untested design, please report back with any issues thank you. 

This is a filament cutter for the ratrig v1 toolhead. It uses much of the same hardware (including the spring) as my previous ratrig toolhead beta2 filament cutter found here: https://www.printables.com/model/695543-ratrig-toolhead-v1-beta2-filament-cutter

And for more information see my original filament cutter here: https://www.printables.com/model/647352-filament-cutter-for-eva3-orbiter-rapido

See the step file for all hardware requirements.

The lever will need supports. Lay it on it's flattest side and support the remaining portion and the (now upper) wall in the blade mount socket. Clean up the supported faces well so they operate smoothly against the lever and blade mounts.
