Ergodox Ez DYI tilted keyboard stand 10° & 20°

I wanted to have my keyboard tilted. So I did the model. Additional advantage is the modularity - if I want more tilt, I can just print different bottom part and slide in the top part. Two parts sit firmly inside.

Also I've put the makeup cotton pads into the bottom part to eliminate the echo, it works like a charm and sounds amazing.

Additional needed parts: 

4x: M3x6 screw

4x: M3 hex nut

to screw in the top part to the pcb plate

I've uploaded the left side, in order to have the right side, just mirror both prints.

update: I've added a bottom with 20° tilt alongside the 10°. The top stays the same.

update2: I've added a bottom with 20° tilt and 8° tent… or the other way around. 20 to the side, 8 to the front.
