This is a case/holder for a single-edge razor. It is designed to hold a razor with a size of 39x20mm (1.53″ x 0.78″). The case keeps a razor locked inside firmly, while still allows to remove and insert it with little force required.
I found a razor to be a very good tool for removing the sticky prints from the bed. I couldn't find any suitable case, so I designed my own. It took me about 20 prototypes to create this one, that satisfies my requirements.
Model is easy to print, it takes about 45 minutes for 0.2mm layer height. The weight is about 5g and I had the best results with PETG filament and 60% infill.
I will appreciate the feedback, so feel free to share your experience in the comments.
Note: Razor should be easy to insert (and remove). If you need to use too much force to do it, there is probably some problem with the print. Using too much force can lead to injuries!
Update (2019-05-11): Added version for ABS material. The original model is too tight when printed in ABS.
