Oneblade parametric guard/extension
prusaprinters
Wanted to try cutting hair with the oneblade and couldn't find any extension/guard long enough, so I parametrized this model from RemyEnder (https://www.printables.com/cs/model/192614-oneblade-philips-sabot). This model has only one parameter “desired height” which you should be able to change to any size your printer is able to print. You will need Freecad to open the Fcstd file, which shouldn't be a problem, since its free.
