Aqualisa Temperature Control ring - pre 1990's

I needed to replace a broken control ring for an old Aqualiser thermostatic shower valve. I asked Claude to re-create the broken part from several pictures and some critical measurements I took from the old part and this is the result - It fits the original valve and works well printed in PETG. It isn't perfect and could do with more refinement, for instance its missing the internal ribs that align with the ribs on the valve and the screw holes are perhaps 0.1-0.2 mm out of alignment - the handle is also different from the original part. Feel free to modify but it got me out of a having to replace the whole valve! Hope it helps someone else as there seem to be no spare parts for sale for these things.
