Vibration speaker standalone mount

A vibration speaker mount that can be comfortably fixed on any flat top/bottom surfaces (under your desk, for example) using a base and that uniformly pushes the speaker to surface by springs.

This one is for any bass speaker 50x30 mm. They are just great for cinema effects, gaming, cymatics experiments, neighbours' revenge and so on!

Please note, that the top cover fits tight, but it should be super-glued because it bears both pressure and vibrations from the speaker and glue spots should not be visible at all. This way the design allows for not using any supports during printing .

3x M4 (90 degree head, any length) screws are used for surface mounting and
3x M3 (90 degree head, best 40mm) bolts to hold
3x OD 8mm springs.

I used this full set of 3D printer bed leveling springs for design purposes:

but you might need to cut your springs or use extra longer bolts (and/or thinner knobs): the kit already contains 30mm, however I recommend 40mm bolts for s
