This is a Corexy carriage I have been spending a few hours on. I took up 3d printing as a hobby to get through my depression and now I am looking at ways to find employment in this crazy cool world. This part was designed in Onshape to suit Mgn9h rails and 20x20 aluminum euro profile. Screws are m3x8 for linear rail and tnut locations. I used F625zz flanged bearings from "Two trees" 19mm tall idlers/cogs and 5x30mm shafts. This Is my first ever design in Onshape with very limited time (6 hours) trying other design tools and finding the tool I felt able. Happy to answer any questions if i missed anything.
