Drag Knife for MPCNC universal mount by FarFlyer

Last crawled date: 3 years, 1 month ago

Update 2016-12-03: increased space for universam mount.
I've remixed the original drag knife from onasiis, adapting for the universal mount of the MPCNC.
You will need:
2x 608Z bearings
2x M3 scews for the blade holder
4x M4 screws and nuts for the 2 part of the body
The round shaft should fit the inside of the bearings tight. You need to sand the shaft until you are able to insert the shaft in the bearings. You will need to apply a force to insert the shaft in the bearings, do not sand the shaft too much, otherwise the part that holds the blade will fall out from the bearings.
The M3 screws do not need nuts, they will fit the hole in the rotor part. I've also increased the space between the two holes, thus you can leave tighten the left screw and untighten only the right screw when you need to remove the blade.
Please note that the uploaded file are slightly different from the printed one in the pictures. I've made little improvements, but I didn't print them again. If you find something wrong, let me know.
I plan to design a blade cover in order to be on the safe side when I have time.
