Razor Holder Boldking v2

I found the original model neat and simple, but it was very annoying that I had to position the razor exactly in the middle. Therefor my remix, that adds two sides, so the razor stays where it belongs. And, it has a screwhole, because I think doublesided tape is not the answer in a wet enviroment. It is designed for Boldking razors, but maybe your razor fits too? The size of the blades can be max 39.5mm wide and 4mm thick.
