▼This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printing

Please leave comments using the talk page. The course runs in the Fall semester. It is not open edit.

When money is hard to come by and other tools take priority, a tool that makes a corner at a 90 degree angle is usually not high on the list of equipment to buy. I wanted to make a relatively cheap tool that can do this. Normally a tool like this can go from anywhere between $10-20 but since it has a relatively small window of use, it is not often purchased. This project was designed for people that cannot afford a more expensive version of this tool as printing this in PLA is approx. $2.00
