Small Suction cup ring for Morbidelli X5 CNC Suction cups

This is the outer plastic joint ring for a Morbidelli CNC X5 Machine.
I made this because my reseller charges me €10 for this a piece.

I print this in ABS on a Flsun Kossel Delta printer
I'm planning on making the rubber for the small cup + the ring and rubber for the large suction cup (but my delta is just a little bit to small...)
