Amiga 4000 CPU card support

This is a CPU card support for Amiga 4000. Note that it is not fully symmetric, the diameter of the cylinder on one end is 4mm while 3.7mm on the other end. I have created it for an A3660 CPU card and the card's hole diameter was larger than the motherboard's hole.
Don't print it in standing format, I recommend to rotate it in the slicing program with 90 degree to lay it on the heatbed in a way that the cut inside the cylinders is vertical. That provides the best printing result if you use zigz
