I made this carriage because i had some issues with the original design (3 wheels) that came with my first delta.
The 3 wheel version tends to needs be tightened with much pressure, to ensure the fitting to the 2020 frame. Also these have the tendency to flip when the drive belts are tightened.
I used 23 mm. (5mm inner diameter and 7mm thick) wheels for this design. If you're wheels are smaller, then don't use this design. Because the fitting will not be snug enough.
Print one to test fit if this works for your delta.
UPDATE
Made one for the 21.5mm wheels. Did not test this one, But i should work distance between wheels is shorted with 3mm.
I have uploaded the sketchup file if you want to adjust the wheel span for different sized wheels.
