20mm T-Slot Rostock Mini by matthewlaberge

Last crawled date: 3 years ago

I built a Rostock Mini that was taller than stock (550mm rods) and noticed that it was not very stiff and would wobble around when I tried to crank up the speed so I decided to make some modifications to the design that would allow me to stiffen it up as well as put my own flair on it. All of the modificatrions are designed to be complete drop-ins for the existing Rostock Mini design so you can mix and match modifications with any Rostock Mini.
The entire design was drawn up in Pro/Engineer and I will make source file available once I am satisfied that the design is complete. I did include a STEP file so you can open this in any other parametric CAD program amd make modifications now.
A complete BOM will be made available soon but to start you out you will need the following.
