Drag Knife DIY Dremel CNC Adapter

thingiverse

This is an adapter for the DIY Dremel CNC in order to mount a drag knife to the Dremel cross-head mount. I used the following drag knife from V1 Engineering: https://shop.v1engineering.com/products/drag-knife-vinyl-cutter I also used (2) left over 3mm nuts and 12mm long screws from the CNC build. I printed the parts with the parting line face down, which worked alright but resulted in a crack between layers during assembly. The crack didn't impact performance though. I did have to do a lot of cleaning of the part, so this design is a work in progress. In general, this has worked really well and I have cut a bunch of vinyl with it.
