Epson Smartpen Collar

I found this design on Printables: https://www.printables.com/model/591959-epson-interactive-pen-collar/files but when I printed it, it was too big for my digital pen, I tried resizing it but if the small whole was perfect the bigger one was not, I decided to take to tinkercad and fix it. This one here fits perfectly on Epson Smartpen.
I printed it using a prusa printer, PETG filament, 100% infill.
