My showerhead holder cracked which meant the showerhead would fall off unexpectedly while in use. This was not only annoying but bad news for my toes too!
Eventually I got fed up, brought out the calipers, and modelled a replacement in Tinkercad.
This is based on the default showerhead and hose but I've included a link here if you need to make changes to fit a different sized showerhead for example. Simply ungroup, make the needed changes and re-group: https://www.tinkercad.com/things/im1qZLpwQr7
I used the overlapping shapes trick In Tinkercad to try to keep the sides smooth which resulted in a nice final print.
I believe this is compatible with all Arrow shower cubicles and is a drop-in replacement for the broken part.
The final model is printed in Add:North PETG Pro Matte at a 0.15mm layer height and took 1hr 39m to print. The comparison photo which also shows the broken part features a draft made in PLA using a 0.25mm layer height. Both used a 0.4mm nozzle.
I used supports since the base is elevated but these came off easily and in one piece by just prying with a knife.
I know this is a very niche part but I hope it helps someone in a similar position!
