Bottle Opener (without metal)

thingiverse

This printed bottle opener model demonstrates an initial design without any metal components for stability. With minimal force required and maximum support at the crucial lifting point, it has been tested to open 15 bottles of German beer before breaking, making it suitable as a temporary solution. Further optimization and alternative designs are being developed. The product was created using Blender with bezier spline curves, accompanied by a downloadable source file. To achieve optimal results, print the item with additional shells, solid top and bottom layers, and a minimum infill percentage. A layer height of 0.3mm, three shells, and five full layers at the top and bottom, along with 30% infill, were used successfully. ABS was utilized in printing, although PLA might be even more effective (although untested). Post-print filing may be necessary to refine the left part of the design if it fails to open bottles due to a tight fit. The design is specifically tailored for bottle cap compatibility but should allow for easy glass passage once the cap is lifted slightly, as indicated in the provided images.
