Customizable Double-Sided Mini Wrench

thingiverse

This is an adaptation of a customizable wrench by gr0b, https://www.thingiverse.com/thing:47842. In this version, you can alter the dimensions of both sides to suit your needs freely. Notwithstanding, the design doesn't function optimally when attempting to create distinct sizes for both sides, so it's best to stick with a variance of +/- 2 mm. However, it will still work with any measurements you choose, although the results may appear unconventional.
