Hex (Allen) Key Replacements

Ever lost the set of allen keys that come with your printer? Try my new design for a printable allen key.  Made in solidworks to print on a flat surface, this unique design and ergonomic shape could be a great cheap replacement for that lost allen key. 

Printed with 4 walls and 20% infill for strength I test printed 6 different sizes and they work for screwing and unscrewing various small screw sizes on my MK3s. Made for the Replacement Parts contest!! Thanks for looking!!!

The 80% allen key is sized for a M10 screw the rest are reduced or increased by 10% until print failure on 50%.  40% is too small to stick to the board well without a raft/brim during printing.
