OXO toilet brush to universal male-to-male adapter

thingiverse

I had several OXO toilet brush scrubbers that needed new heads, but buying them from Amazon would have cost $13 each! Fortunately, universal toilet brush scrubber replacements are significantly cheaper, especially when purchased through websites like wish.com. This adapter allows me to use universal female toilet brush replacement heads on the existing female OXO handle. To ensure a secure fit, I glued the adapter into place inside the handle since it seemed to be a tighter fit on the brush side.
