This is a bottle holder I made to hold glue bottle's upside down, with easy removal for use. The bottle diameter this was created for is 40mm, if your bottle is larger or smaller just scale up in x and y a little and just to be sure it fits, only print the first 2mm and see if your bottle fits before printing the whole thing,

No supports are required, but I don't recommend printing at over 0.2mm layer height as the bridging at the top may look messy.

0.8mm or 2 perimeters, with a 0.4mm nozzle works fine for me.
