I recently bought the tisken shower basket but it sucked. Unfortunately not in the literal sense so that the box dropped after a few minutes. So I quickly designed a replacement hanger so that I'm able to mount the basket with 3M DualLock "stickers". It works like a charm.

Just print this as is. I designed it to be printed without support, hence you have to remove the one layer thick bridge in the slot. This is easily done with a deburring tool or a rasp/file. The 26mm wide bridge may print wobbly and I wasn't sure if the 3M will stick to it but it went absolutely fine for a couple of months now. The depth is slightly less than the thickness of a sandwiched DualLock piece (a fraction of a millimeter) but still gives enough room to securely mount the basket.

I include the freecad file so you can easily modify the thing if you need to.

I'll update the description in the upcoming days.
