Tree Stump Speaker Stand

ATTENTION: When using heavy speakers, consider adding some rubber coating on the sphere, to avoid damaging your speakers by falling.

This is a remix from https://www.thingiverse.com/thing:398515

The sphere to push into the joint of the stump has an insert for an M6 bolt to screw into the speaker bottom.
Go for a bolt with 20MM length of the threaded area, it'll stick out by 5MM.

If the joint is too loose you can also just tape it some or w/e to make it a bit larger and stiffer.
