Summary

I needed a finger brace to wear on my pinky finger while I slept and quickly whipped this one up. I could design it better than this, with nicer curves, but it would require more time and need supports to print whereas this one is already done and if you print it on it's end, it will print without support on an FDM printer.

An added "Feature" I found is that if you rotate it 180 degrees on your finger, you can bend your finger without taking the brace off.

At first I just made it a cone shaped cylinder but by changing it to what I have uploaded, it fits the fingers joint better and won't make my finger sweat.

Remember, I am not a doctor, so first see a doctor and get their buy in on wearing this or you may end up doing more bad than good!

I have included the Fusion 360 file in case you want to modify it to fit your finger. It has five parameters. The code file uses the dimensions in parentheses and is sliced for an Artillery Sidewinder X1 - don't use it on other printers. Slice the 3mf file for your printer.

• BackDia: (19mm) This is the diameter of the part of your finger closest to the hand.
• FrontDia: (16.8mm) This is the diameter of your finger closest to the tip of your finger.
• FilamentDia: (0.4mm) This is the diameter of the nozzle you are using to print.
• Thickness: (1.8mm) This is how thick you want the ring.
• Length: (34mm) This is the length of the ring in case you have long or short fingers.

Print settings

• I sliced using CURA and printed on an Artillery Sidewinder X1.
• 2 walls
• 0.2mm layer height. (0.12 gives smoother finish but takes way longer)
• 10% infill (Doesn't really matter much as it's mostly solid wall).
• I used PLA.

You might notice that my print looks a little rough. It is. I think I had some old filament loaded and it was stringing a ridiculous amount. The brace worked though and so I haven't bothered to print another.

230413 UPDATE:
I printed a couple more using some new, clear filament, and the results were way better. I also changed to a 0.2mm layer height and the result was more than adequate.
I also dropped the finished braces into a cup of boiling water, pulled them out with a chopstick and then shaped them to my finger while still soft. Be careful doing this or you may burn yourself!

Please give me a like if you decide to use one of my things. It encourages me to share more. Better yet, post a photo of your make.
