Lens Filter Step Up Ring (39mm to 58mm) - TTArtisan AF 27mm f/2.8

thingiverse

This is a step up ring that adapts 39mm lens filter threads to 58mm. The TTArtisan AF 27mm f/2.8 uses the odd 39mm thread, and I wasn't willing to hunt down and buy another CPL filter, so I want ahead and designed my own. This is printed with a HALOT ONE, and Sunlu ABS-Like Resin. It takes about just over an hour to print one, so you could print multiple ones in a single go if you want to fit more onto the print bed.
