My lens collection is growing, so I made these camera lens holders for my pegboard to keep everything organized. 2 sizes are included, holding lenses with a maximum diameter of 72mm and 76mm. This has worked well for all my lenses, which are between 58mm and 72mm size lenses. Of course you can use it to hold anything else that fits as well! I've used these for 6 years and they haven't budged. They were printed solid with MatterHackers PRO series PLA

No supports required, unless your printer isn't great at bridging.
