pool ladder step replacement
thingiverse
This is a supports to fix and even enhance broken steps of my pool ladder. The stock ones became porous and eventually broke. I used CF-PLA with & 0.8mm nozzle and 3mm thick walls (about 1 hour print time). It should withstand chlorinated water for years. You obviously need two of them per step, and you can tune the thing with openscad (sorry, no customizer here). Note that I recommend to print them without any support by rotating them as shown on the last picture, it also makes the part sturdier.
