Thank you for sharing this file. The cap fits great with no sanding. The inside diameter of cap I printed from your file was .07 mm smaller than my store bought one.

If you like this, you should also check out gcardinals Lens cap. It doesn't need sanding and fits very well. Also the side connected to the mount is a bit wider (similar to canon lens caps), which helps it to proctect a bit more of the Mount. Very well done.

Printed and it wont fit any of my Nikon lenses. Printed on 0.4 20% fill and 2 shells. PLA.

Hej! Sorry to hear that. Just out of curiosity: Did you read the description? Especially the part where you have to sand it down to fit your lens properly?


Hi, Sebastian! Yes, but "sand it down" and "remove at least a 1-2mm of surface or all-round is not the same :) also sanding down is not a good option to begin with, damaging surface of the cap will inevitably lead to more dust and particles separating from the part and ending up on the lens or worth making its way inside the lens. I think to have a part that just fits is essential here.

Hej! I don't want to offend you, but why did you print it in the first place then? It says: It won't fit, if you do not sand it down. And where did you get that measurement of "1 - 2mm" from? It's a few tenths of a millimeter. It'll smoothen the face that goes to your lens. Just clean it under water afterwards and there'll be no particles left.
I did not create a new version with perfect measures, as the sanded down versions fit so well to my lenses (Better than some of the originals). But I would appreciate a version that would fit out of the printer.


Hi, Sebatian! I finally my printer operation again, tested and uploaded a fully printable lens cap, you can check it out here: http://www.thingiverse.com/thing:114331http://www.thingiverse.com/thi... . Thanks for inspiration!

Hej! Looks very good. At the moment I have no access to a printer, but I'll definitely try your cap. I guess it provides more grip for the hand. And I really like that little overhang. I think it'll give the back of the lens more protection than the nikon(ish) designs.


I made a couple of these. Well done! I think I would have liked it better without the "N" (It didn't turn out well on my printer) but it does the trick. Thanks!
