F Mount Lens Cap

prusaprinters

<p>As was the reason behind my front lens cap design, I had acquired a few vintage Nikon lenses that did not come with back caps. Designed this to keep these lenses in the best condition I could. I had a few official caps that were used for base measurements and have iterated a few times to arrive at this version with a better profile. This back caps align with the f mount and twist to lock on the mount. I hope that it can work well for you if you choose to use it.&nbsp;</p><p>I do not print with supports BUT I could see were they may be needed. I would recommend trying the print with out supports.&nbsp;</p><p>The Fusion 360 source files are attached if you want to customize these with your lens mm on the back. (e.g. 50 for a 50mm or 70-210 for a 70mm-210mm, etc.)</p><p>Print process for 2 color cap:</p><p>Use the settings in the attached profile. Let me stress that it needs to be printed with a .2mm layer height for the following instructions to apply.</p><p>The model has the loosen/tighten symbols where it is cut into the part by .2. I do the same when I add text. I add text to the top of the cap and print with that side facing down.&nbsp;</p><p>When slicing I have add a color change after the first layer so that the loosen/tighten icons and text stand out.&nbsp;</p><p>&nbsp;</p><p>Additional Notes: I have used PLA for all of my caps and not had any material based issues. I have tried PETG but found the prints a bit more stringy and did not want to risk getting any plastic into the lens mechanics.&nbsp;</p>
