Rally tire rings with Dunlop pattern 3D print model

Set of 13 rings with rally racing tire pattern.

Sizes from 16 to 22 mm with step 0.5mm.

Ready for production. All 3DM files are produced in 6-th version of Rhinoceros. All STL meshes prepared and diagnosed without bad edges etc...

Rings are pretty massive and I can easy remodel it to slightly thinner variant ( from 1mm of base thickness to 0.7) but only on demand.

Model volume varies: 0.544cm^3 for 16mm; 0.560 for 16.5; 0.575 for 17; 0.589 for 17.5; 0.605 for 18; 0.620 for 18.5; 0.637 for 19; 0.650 for 19.5; 0.664 for 20; 0.680 for 20.5; 0.695 for 21; 0.710 for 21.5; 0.726cm^3 for 22.
