I made this safety razor storage tray and included the gridfinity system. The individual blade holder slot is spring loaded and you can fit a hefty amount of blades in the slot.
The spring sits in the slot loosely under a 1mm lip on each side. (I printed without supports and had to do u small clean up on the underside of each lip.)
To install the spring put it in the slot sideways and then fold it over like a slinky. (The smaller end of the spring faces the front and the very end of the spring will face the front right hand side.)
I also put in a small slot to hold a sealed pack of 10 blades. I have left a lot of room for remixes and modification to fit your specific razor. There is also a small drain hole in the front to eliminate the blade sitting in water and potentially rusting.
I have included the step file.
Thanks.
