There are two models. 01 is for the small original water distributor and 03 is for a flat but wider 58mm one from a NUOVA SIMONELLI machine that I just happen to have (Part No. 1326037) that I use in combination with an IMS shower screen.
Printed using BASF Ultrafuse TPU 85A and 0.8mm nozzle @ 20mm/s and 210C nozzle with 55C bed.
