Prusa-i3 spool/accesory adaptor

I threw this together so I could use one of these guys https://creality3d.shop/products/3d-digital-spool-rack-ssingle/ . Works excellent and I figured it could be useful for mounting other gadgets as well. So here you go!

Printing is a bit finicky since this is best printed on its side. That messes with the M4 screw threads. I made them a bit tight to get better grip. Make sure to use 4 perimeters vertical for strength. You can also try printing with the threads down, but that is probably going to lead to part failure.
