This is too tight for my GT2 belt to fit.
I printed it on a bq Hephestos prusa i3 slised in cura at both 0.2 and 0.1mm layerheight.
I also increased the filament diameter in cura, but its still too tight.
A 20x20x20mm testcube is printed correct.
Could you upload a version for a bigger belt clearance?

Here's the link to the fusion 360 CAD file :
You should be able to modify it.


Did you use ABS ?

Real dimensions on this Item should be 3 % less than the CAD one, maybe you could rescale to 103 % (approx.) on X, Y and Z in CURA so it should be OK.

Anyway I'll upload a link to the CAD version (Fusion 360), then you'll be able to modify it the way you like. I can't access to my cad files for a couple of weeks. Feel free to ask again If I forget to upload it.

Let me know.
