Small Bottle Opener

thingiverse

There are some nice prints showing up here. I'll add one to the list. My arthritis makes it difficult for me to open the screw caps on some smaller bottles. One can find an example or two on Thingiverse, but they are each either too large to print on my machine or otherwise unsuitable for the job I had in mind. So, I used 123 Design on my Mac to make one up from scratch. As you can see from the photo, one of the squeeze arms is shorter than the other. I had to shorten it this way so that it would fit onto the bed of my M3D printer. As it turns out, the asymmetry is no disadvantage. The longer arm fits the palm and the first 3 fingers fit the shorter arm quite nicely. The little finger wouldn't supply much power anyway. I used 123 Design to design and prepare the .stl file. M3D printer, M3D Fio software, Macbook Pro running the latest operating system. I printed it in PLA, Low Quality, Thin Hollow Fill, no raft or brim, no support. Took about 4 hours on the M3D. I didn't clean it up at all for the photo. I think the tiny bumps along the upper edges of the handles are an artifact of the low quality printing combined with a 2mm filleted edge.
