Solidworks STEPFILES rig testing for UM2 feederI think there is still a wide spectrum of very interesting possabilities about how we can handle plastic filement and how it is being fed into a 3D printer.This is a simple accurate test rig for 3d modelling for the back openings of the back panel of an ultimaker2 3d printer.This is useful for me and maybe will help others get deeper into their own designs.Ian :-)
