I resized the original design for smaller washers (13,5x45x4mm)
You have to stop the print around 50% and insert the washers. The first layer over the washers will not look nice, but the second layer will fix that, the end result looks great.

I put the print pattern up so the pattern would be prettier because I use a textured print plate.
