This is a very simplistic V-block that isn't really intended to be used, although I guess in theory it could be used. It is designed in inches so you will most likely need to scale it if you're using a metric based slicer like Cura (and I'm sure most others) I'm no printing expert, and I'm not working with the best equipment, but I went slow and steady with this, trying for the most accurate surfaces I could get. Used 20% infill, but really any level would work, and didn't use any raft, brim, skirt, etc. This was designed in MasterCam as a simple project to play with the extrusion feature.
