TPU FOOT

I use it on my Sovol SV08 first and most to Elevate my 3D printer, in both senses!
So you can use it as a raiser and, or as a anti/sliding 
When you print fast the printer tent to slide on table so with this foot you limit the movement

Inspired from the automotive industry we came with this design. 
No need for support!

0.2 Layer Height
3 Walls
5 Top
5 Bottom
10-15% Infill  - Gyroid

Any TPU will do the job but if you can try to use lower than 90A because it will act also as a nonslip ;)
