Modified version of the original to fit the nut size that I have used previously (¼-20) and reduced the plastic between screw and nut, which also reduces print time.
Printed mine with PLA and have included a print file and the model. Print file has infill set to 40%. I think it is fine, but 60% would probably be better/stronger.
The author remixed this model.
I chopped the bottom 2 mm off and crudely added material to the area where a nut is supposed to go so it fits standard ¼-20 nuts.
New Model:
2.8 Is the same as the 2.7, but I only chopped 1mm off of the bottom and took the thickness down 1mm, so the hole where the nut goes is deeper. I did this because I noticed that the nut was sticking out a little bit above the plastic. In my use it hasn't hurt the camera, but for those cautious I have included this new version.
