This is an adapter for cheap 25W 50mm little base shakers to fit the P2000 Simagic Pedals.
You will need:
I have tested on my rig and the shaker clears the brake fluid reservoir when braking, but I guess it all depends on the travel you have in the pedals.
Not sure if it's just coincidence, but I had one printed out of PETG and one in PLA. The PLA one made a very different sound, more mechanical, the PETG was more dampened and deeper. So if that happens to you, just print them in PETG.
The author marked this model as their own original creation.
