So I wanted a small, and thin friction hing for another project, and I couldn’t find the metal ones that they use for the iPad’s Magic Keyboard case. So I design my own the parts I had on my desk.
The smallest nut that I had was 4mm wide which really limited how thick the design can be. The result is this
It folds flat at measure at a maximum thickness of about 10mm
It works a lot better than I thought it would, especially since this is my first prototype print. Need to figure out some things, like to stiffen the arms and to prevent/reduce twisting.
But as a basis to start from this works nicely. I think if I add a TPU washer on the back end, I might be able to get it stiffer and more consistent feeling. But I’ll do that at another time.
You might be able to make it much stiffer by adding more of the arms parallel. The force should be consistent when you tighten multiple of them with one screw.
Nice! This is really impressive for a first prototype print. I’ve been printing for over a year, designing small brackets and such for maybe 6 months, and most of my designs are just one solid piece. Something with moving parts is awesome!
Can we ask what the project this is for is, or for a link to this model?
