Dayton BST-2 Bass Shaker 4040 Flush Mount

I resized the bolt holes to fit M4 and M8 more tightly. The M4 holes are now also countersunk so you can mount the Shaker flush up against any width of aluminium profile.
Slightly redesigned the tabs that stick out to be smaller.

Since the BST-2 itself has counter sunk holes, I added a counter-counter sunk thingie that you can place in there so that your nur sits flush. You need 4 per shaker.

Expored as .stl and .step for easier editing.

Thanks PandaAttack for the original design!
