hi I designed this cover for Gillette Mach 3, but it can be used for other models with similar size as well. You can print in two modes with and without support.
If you want it to be printed with support, just print A and B.
If you want it to be printed without a support, print A, B1, and B2, in this case, they must be screwed together after printing. I printed with the support and the support was removed very easily. I only selected 10 percent support density. print and enjoy. update 7/8/2022 Add new photos and new design : (ok A) - (gillette B) The blade pack is much better fixed in (ok A)
