Đầu kẹp nạng kiểu vít (Ø20.3)

I made these to help someone that currently has to use crutches. They have a diameter of 20.3mm.

I wasnt happy with the available designs because they come loose on their own to easily, so the clamp here actuallly uses a fine M12x1 Thread. This means that you'll need a properly tuned printer to print the threads.

I printed the Clamp and Screw in PLA and the clip in ABS, but with prolonged use they'll probably wear out eventually, which is part of why i didn't want the clip integrated into the clamp. The clip is mounted with two M3x10 Socket head screws, threaded directly into the plastic. This should hold up fine unless you're trying to hang off the thing…

The thing youre clamping this onto should probably be at least 25mm thick or so up to maybe 40mm. You might need to add some grippy tape or something if you're not clamping around a non-slip Tablecloth.

Anyway yeah this print is pretty situational, but maybe it will help someone else.

Prints without support and the STLs are in my recommended print orientation (especially for the clips, some slicers automatically place them onto the large flat surface but that's wrong because of the layer orientation)
