Velcro stickers and rubber feet from the 1-Euro store, and the handle of an old toilet plunger.
I had to flatten the plunger handle on one side to make more of the velcro stickers connect.
With tenting I really would like to have more aggressive staggering for the pinky column though.
Fun solution!
I went with fixing bits of Fishertechnik cladding plate to the bottom plate of my Lily58, and I’m working with plus pegs and other bits to find the ideal height.
