Summary

Granted I know no one asked, but let's be honest the only thing this little MAME Machine was missing was Pinball style side buttons. When I built my first one I drilled them but because of the fragile nature of 3d prints. I modeled them in this time(which was ironically faster. I will update with better pictures of my new build.
Printed on my Creality K1 Max
Printed in Elligoo black PLA.
25% infill.
.2mm layer lines
support enabled.

Edit: Moved the holes further back due to a clearance issue with the Sanwa joystick.
for those that printed my first design(like I did) and do not want to reprint three whole lower half again. I have added a six button panel with the joy stick counter sunk for added clearance. I also counter sunk the buttons so they actually lock into place. keep in mind with the new control panel the joystick need to be attached with M5 screws instead of M4 screws. Update: unfortunately I found even with counter sinking the Sanwa Joystick, I found that there was still a slight clearance issue with the left . But by carefully grinding a notch into you can gain the needed clearance so both fit without losing the functionality of the button or the joystick. I've included pictures of how you should grind the buttons. If that seems like to much trouble then you should probably print the newer version with the buttons further back.
