Arcade joystick controller case USB 10 buttons zero delay

I created this arcade controller custom case, because I was looking for a controller which is big enough to accomodate space to rest your left/right hand on while playing and which also is printable on a standard size printer with max. 20x20cm bed. Couldn't find anything fitting my need, although there are quite a lot other design here on thingiverse.

However maybe somebody will like my design and have the same requierements.

Easy to print:
- 2 top pieces
- 2 bottom pieces
- 2 connector pieces

Hardware:
- 30x M3 screws with at least 8mm length
- 4x M4x8 screws/nuts, alternatively M3 for screwing the joystick in place (the buttons snap in place without additional hardware)
- 4 optional 4 suction cups with M4 threads (works really work preventing the controller sliding around

I used the zero delay arcade controller joystick kit from Banggood:
