Bottle Opener (without metal)
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
This design is a prototype of a purely printed bottle opener design, which means you don't need to add a coin or other metal parts for stability. It's designed to require minimum force and has maximum stability at the critical point (where the cap is lifted).
My printed prototype withstood about 15 bottles of my favorite German beer until it broke. So the current version can only be seen as an "emergency" bottle opener but nothing which lasts long.
An optimization to this as well as an alternative design (also without metal) is under development.
Please read print instructions for good results!
The model is designed in Blender with bezier spline curves, the Blender source file is also available for download.
