for those curious, the marquis at the top was made using MakerWorld's #lightbox feature (this was before the current AGPL violations debacle). The decorations on the side were actually made using the same tool - but by taking the object in the exported 3MF and dropping most of it below the build-plate until only the colored picture remained printable.

Thus I made some pretty cool 2mm thick 3D printed pictures which could be glued onto the walls for that 80's arcade feel.

Also I think having an arcade cabinet and playing classic #MortalKombat in my living room is very, very #metal
There's one more missing piece. I ordered a #SindenLightGun to complete it.

The #LightGun (and pedal) I'm most likely thinking of is the #SindenLightGun

There's also the AimTrak (less accurate?)

And the Gun4ir (very expensive)
