Do you have trouble with your pop/coke/soda habit?
Does your significant other, roommate, friend, pet or other entity require assistance opening their refreshments?
Do you get tasked with opening those bottles of carbonated drink or need to task others?
Do you want a 50/50 chance that it will stop or get easier -- or just need a fancy new fridge magnet?
Well then - this is specifically for you!
Print the BOTL OPNR!
The BOTL OPNR helps you grasp standard 28/400 spec* plastic bottle caps, and it has magnets to stick it to your refrigerator door so you won't loose it in the kitchen junk drawer.
The OPNR has an enclosed recess in each 'handle' that is 3.2mm in diameter and 6.4mm high - which should hold 3 or 4 6mm by 2mm round magnets - these are the same ones that are used with the Gridfinity things
Print it in your filament of choice at a 0.2mm layer height - and pause the print at some point before layer height 6.6mm (around layer 32/33 for 0.2mm) and place the magnets in the recesses. No glue should be required, but if you have a steel nozzle you may want a drop of glue to keep them in place.
When done, you can marvel at the near magic of seemingly magnetically attracted plastic! impress your significant other, roommate, friend, pet or other entity!
*many two liter bottles and bottles of other sizes that are commercially used to hold consumable liquids have caps that have a 28mm outside diameter.
