Gridfinity Wowstick 1F+ 6u height

I really like the original design. However, after printing, I found out that the demagnetizer is sticking out and it's difficult to stack another gridfinity block on top of it. Also, I want to use it in combination with 6u high storage bins for screws and stuf.

I've modified the Fusion 360 file and found that the height could be set with a parameter. However, it wasn't correctly working. I corrected that and now it is possible to set the height without strange side effects.
