2020-03-14 (Sa) Electro Knife for Simulated Combat EleKSCo

I created a 3D model based on yesterday's sketches. I thought there would be lots of extra room so I could have a shallow slope, but I quickly filled the entire square tube. The idea behind the design was that I could seat the switch at the top in the cavity that looks like the top half of a capital H, and when I add the little wedge, it will compress itself into the corners of the pipe and pop the switch out a hole. There has to be enough clearance for the switch cap to fit through the tube so the wedges cannot be too steep. Both inclined planes have a hole so that a bolt will draw them together.

The device printed well, and my switch fit neatly inside the cavity, just as I had hoped. The clearance between the top of the print and switch turned out how I expected, and the lip of the switch cap came to the top of the tube and plastic part.
