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

Common Problems and Solutions[edit | edit source]

  • Be careful removing the main Cornering Tool piece from the glass bed. Use an exacto-knife and carefully remove to not break the glass.
  • Be sure to use sufficient adhesive on the glass bed so that the main Cornering Tool piece does not have its edges bow upwards.

Cost savings[edit | edit source]

  2. Estimated Cost: ~ $1.50 depending on filament price
  3. Commercial Cost: $10-20 | Home Depot's Wall Cornering Tool
