![]() ![]() Because we didn't have the option to buy another mount (we were 2 weeks before the deadline, shipping from USA to Romania takes 2-3 months), the 3D design team proposed that we print one, with double thickness. ![]() The double thickness Motor Mount: last year we wanted to mount an extra motor on the robot for the ball elevator, but we've discovered that we don't have any aluminium motor mounts left. Also, all the holes in our robot and in our models are M4, because they are the standard screws in Romania, and Imperial screws are very hard to find and very expensive.ฤก.We learnt that, even if PLA breaks easier than aluminium or steel, doubling the thickness of some parts like the motor mount or the 3D printed gears can help with the strenght of our pieces (PET-G would have helped also, but our 3D printer cannot print in PET-G).Other pieces, like the end cap or the double end cap for our 20x20 profiles are very easy to design if you have a calliper and a profile next to your computer, because you can get the exact measurements very fast and easy.Some pieces, like the pieces from the Tetrix kit are very easy to print because you can find them in the virtual kit.You almost never need more than 75% infill on a piece, it only increases the printing time without adding too much strenght.Things we have learned while designing and printing those repairs: We will try to improve our 3D models for the phone support, for the end caps, and for the strain reliefs to provide better functionality.We will continue to design and print 3D replacements for our robot, because things always break on our robot. ![]()
