Octo-Cap
thingiverse
I was trying to think of something to do with all of my octopuses, and this idea amused me greatly. Now I look forward to cleaning my print bed. I hope it amuses you too :) this was made for the Cute Mini Octopus v5.5. I haven't checked v5.6 yet, so lmk if I need to make some other versions. https://www.thingiverse.com/thing:3495390 two versions are attached with different thru holes sizes. one to fit a #4 thread tapping screw (mcmaster 90385A108), and the other to fit a M3 x 12 screw/nut. simply drill two holes in your IPA Cap (or other cap of choice) to fit your screw. to fit the Octo-Cap adapter. Mount the cap to the Octo-Cap, secure the Cap/Octo-Cap to your bottle. check your orientation so that the Octopus faces the right way when the bottle is closed (if you care) and glue in place. I used super glue gel - allow to fully cure. https://youtu.be/SSvyqYY3El0
