Cup holder piece for the popular Aliexpress fastener

thingiverse

I had a nice cup holder for a baby stroller from Aliexpress which also came with the fastener part. Unfortunately the removable cup holder was lost so I created a replacement for this fastener. Works very well, the holder is sturdy and can be removed. For printing I placed it upside down and used some support. The base from the inside is not perfect but that is alright. If I would loose it again and needed to do another print, I would probably split it in two and then glue together to avoid any need for the support.
