Used 2-4cyli for the outside. Overlapping triangles removed. Outlines thickness corretced.
*try to use some 1-4chrd or 1-8chrd prims to pad the inner most ring to the surrounding geometry, otherwise there will be gaps at higher resolutions
*these 2 vertices can be merged to their respective outer corners:

Sorry I didn't see it last time, but there is an obsolete ring primitive. Please change this line

to

Everything else is fine.

if you replace the bottom 2-4 disc with a 2-4 chrd you may get rid of that triangle

*Found a gap in the pattern. The 1-4chrd at the top of the inner area is turned 45 degree. Turning circular prims at angles not multiples of 90 degree causes rounding errors, thus the gap.
The idea to use lesser prims is good, but in this case it's better to go simple:

Also did you try if it's possible to scale (and position) the logo minimally different to get rid of the high accuracy decimals?

Please ignore the comment about the logo scaling, accuracy is fine (caused by the chrd prims).

Did you use Unificator on this version?
There are tiny gaps/overlaps.

This long stretched triangle is caused by the logo file (which uses a similar long quad). I guess it would be best to wait for the logo file to be fixed or certified, before continuing on this part.

I have updated the geometry of the logo primitives. This file should be adapted fit to the new geometry dimensions.
Gaps around the logo.
Sticker design adpated to the new logo primitves. Gaps removed.
*still 2 tiny gaps here:
2 5 -4.38402 -.25 4.38402 0 -.25 6.2
2 5 0 -.25 6.2 4.384 -.25 4.384
2 5 -4.38402 -.25 4.38402 0 -.25 6.2
2 5 0 -.25 6.2 4.384 -.25 4.384
2025-02-05 19:52:43
Have checked the part. Dont see gaps on the mentioned position. Can you please clarify?
The tiny gaps were caused by different rounding between vertices and prims.
I solved that, created a stickerback subfile and corrected the dimensions from 0.9 to 0.8.

*you should use a 2-4cyli prim for the round side surface
*there is an overlap:

4 5 -7.2 -.25 -7.2 7.5 -.25 -7.5 7.2 -.25 -7.2 -6.975 -.25 -7
*judging from the photos, the silver outline should have the same thickness everywhere, the top ring is currently thicker
*these 2 vertices can be avoided: 2 5 7.2 -.25 -7.2 -7.2 -.25 -7.2
