Sofa Raisers [stackable]

So i've made some stackable sofa raisers to adjust the sofa to the height needed for the cleaning robot to get under it.

I've also made different shapes and sizes.

Current available forms/sizes:

Circle (50mm; 60mm)
Square (50mm; 60mm)

“D50” means the inner diameter of the raiser - so your actual sofa foot should be D=50mm max.

Please Note:

When raising your sofa with these, make sure that all is safe (dont stack too high; consider glueing the pieces together when using many; make sure your print settings are right and you get propper layer adhesion)

Print Settings i've used:

at least 30% infill
printed the stack and top parts with normal PLA
printed the foot part with TPU
no supports needed
