Hi, im new to 3d printing and would like to use this for a Coderdojo. There is a small gap in my prusa mk3 prints on top of the black ring - the ring is not closed. I was not able to import it to tinkercad - will try again tomorrow. Can you provide another model or provide a model with works with Tinkercad ? Should I print it bigger or use a specific slicer option to get this fixed ?

Concering tinkeracad, I used meshmixer and uploaded it sucessuflly. TInkercad answered on facebook instantly in parallel and provided this model on tinkerad as well - not sure what went wrong the first time.

There are a couple of easy ways to fix the gap you're seeing. One is to use the "Open in Customizer" button and make a custom version with a bigger border parameter. The other is to use the "Detect Thin Walls" setting in Slic3r. The photo above was taken off the default model sliced in Cura, which didn't have the gap problem, but I saw the same as you the first time I printed this model via Slic3r.

Thanks a lot for your fast feedback ! I came to the same result after printing the device two times - Im now able to read the shape print view in slic3r. Maybe you add this little hint in the description as well ? Its a great learning example - my first two color print.
