I have built some models in order to build a ruggidized waterproof phone case that fits a variety of devices. However in doing so i design the pieces with a variety of features to allow them to be used in as many applications as possible. There small foot print and the congruency of the parts should allow for multiple print heads to print many pieces at the same time with only one print controller. I would like to point out a fair amount of ignorance on the computer science portion of this i/e the programing design etc. but some of the models I have built are available at https://memento.autodesk.com/users/josh-hall. Unfortunatley I have built these models on meshmixer and in order to get the boolean difference to work i had to make the parts solid which aparently puts lots of triangles in the mesh, and has the unfortunate consequence of making them unconvertable to a spline model.Such that, I was unable to edit and clean them on fusion either due to the program or my lack of experience most likely both. However the parameters could be used to make lining up of the parts much easier and make them fit together with much more ease. Unfortuately I didn't know of either fusion or parameters until I had done around a hundred hours of work. The models of memento I am specificly having issues with are outer shell rail snap rail rib with pilot holes and the extrudable slide.
