The file 'Magnet Insertion Tools 3D Printer Model' is (3dm,stl) file type, size is 6.0MB.
I use a lot of 3mm (diameter) x 3mm (height) cylindrical rare earth magnets to hold 3d-printed puzzles and models together. The magnets can be hard to work with-- they are too small to comfortably grip, and it often takes some force to get them to fit into the holes on the model.
These tools solve the problem:
This tool was developed as part of the project `Motivating First-Year Calculus with Robotics' supported by the National Science Foundation under DUE-12-45540. For more from this project, see my webpage.
