Replacement of a "Giacomini R450X001" regulator for radiators. The original's mount shattered into pieces after (I assume) 20+ years. However, the original mount has rather tight dimensions and I couldn't print it in a strong enough fashion to withstand fitting and usage.

Therefore I opted for a (hopefully) more durable, complete replacement that I could cleanly print on my FDM printer (Prusa Mini, 6mm nozzle) without using too much support material.

The mount snap-fits to the radiator's valve (a little heat helps).
