This is a mounting plate I designed for a virtual pinball machine (vpin). It fits into the standard Stern Spike 2 DMD and speaker panel.
It supports 5.25 speakers and has fins surrounding the plate to support addressable LEDs to surround the speaker.
Print in clear PLA or similar to let the LEDs shine through.
Uses M4 bolts and nuts to mount the speakers.
Two files provided, one for each side.
Not sure if this is suitable for a real Stern Spike 2 machine; my use case is a virtual pinball machine that is a Stern replica for size and parts.
The author remixed this model.
Removed mounting holes for the DMD panel that typically aren't needed on a vpin. Added LED surround. Added hex grid fill for the speaker “hole” to enable more light display.
