Needed a shower soap dish for the kids so I made this one. Has two recesses on the back for double sided mounting tape. I used this: https://www.amazon.de/gp/product/B00IDAQA8K/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 , but any waterproof tape with a thickness of .8mm or more and a width between 10 and 19mm should do. Holes inspired by Fotone's soap holder design.
No supports needed. Slice with variable layer height for best results.
