Isobutane Ring

I was tired of hearing my fuel canister bounce around inside of my ultralight backpacking cook kit so I printed a TPU ring to go around the canister base, it deadens the sound and adds extra grip while cooking  on smooth surfaces. 

I checked it on the canisters at the local sporting goods store and it should fit on all 4oz canisters. 

I printed it from cheap 98A TPU that I had around from another project with the following settings. 

.20mm Structural  

0% Infill (Its so thin I don't think it has any infill)

Ironing enabled on the top surface only

10% Overlap

1 Perimeter

Random seam position

0 Top solid layers
