Threaded Lens Cap Holders for Camera Strap

thingiverse

Inspired by Teds lens cap holder I created my own design, because I wanted a few improvements: * a __proper thread__ that holds the cap as good as the lens or filter itself (0.75 pitch) * closed bottom to protect the cap (thin bottom, therefore not really more filament) * option for two different sizes of caps when changing the lens (__double__ version) * proper fillets to avoid sharp edges I've tested the holder in my recent vacation trip and it turned out to be very useful. No more searching for the cap in the pockets and due to the thread it held on the holder as good as on the camera - never dropped it. The holder is designed for a 40mm camera strap and can be mounted easily without removing the scrap (just fold it and slide it through the gap) Besides the "__single__" version I created a "__double__" with two rings which can either hold the cap of my normal zoom or the big tele lens. And as the cap of my big tele lens has a diameter of 86mm I also created a "__slim__" version, which is smaller as long as the large cap is not mounted. Disadvantage of the slim version: cap doesn't hold as firmly, but I never lost the cap so var. The single version I provided in common lens sizes: __55 mm__, __58 mm__, __62 mm__, __67 mm__, __72 mm__, __77 mm__, __82 mm__ and __86 mm__. For the double and slim all combinations would have been too much, so for now I only uploaded the versions I use myself. (__67mm+86mm__ and __55mm+62mm__) __Leave a comment if you need different sizes__*. P.S.: I haven't used it like that, but as the thread has the proper 0.75mm thread, you could also use it as filter holder (need to screw it on and off every time though, not as fast as mounting the cap. *) sorry, didn't do it in SCAD - proper fillets everywhere are quite cumbersome in OpenSCAD - therefore now easy self customizing, but I will provide more variants on request
