This is my first 'design' ever. I used Tinkercad. I really wanted to make something with moving parts that could be printed in one print, so I thought a hinge would be a good thing to try. It is, of course, an exact replica of any standard fixed pin butt hinge you'll find your house doors hanging on.
3 Sizes: 100mm x 25mm 70mm x 25mm 70mm x 20mm It was requested that I add versions without holes, which are now available too.
They print flat with a tolerance of 0.4 which I found was quite tight and my printer had no trouble with it. Fancier printers might be able to get it tighter. Be careful when scaling the whole thing though as it will stretch hole sizes and the tolerance will be different.
Infill amount totally depends on the weight of the door you hang on it and how strong you want the hinge to be.
Let me know if you found this useful! I'd love to see your prints! Enjoy!
