This is an OSAT project taken off the OXFAM equipment catalog. All STL files are orientated properly for printing. This design is meant for quick removal of bolts and nuts. Significant force should not be applied while using this tool; fasteners should be broken loose first using a breaker bar or ratchet. Two of the "Joined_Corner" pieces should be printed.

Materials and methods

Plastic: PLA used for prototype (Others may be better suited for this application)
(Optional) Epoxy: JB weld used for added strength

- 100% Infill for strength
- 2 Line Shell Thickness
- 210 Degrees Celsius Printing Temp
- Cleaned up edges of prints using a knife
- Test fit then epoxied and assembled
- Parts should be snug when assembled and seated using a hammer
