Solar filter holder 72 & 77mm

This is a print in place filter holder designed to make it easy to make filters using material like Baader Astro Solar film. It's designed to screw into 72mm lens mounts. It's not threaded with the idea that the first few uses will tap a thread onto the filter holder.

You'll need a fair bit of support as both plates start printing off the bed. I will use interface support.

So far the print is untested. I'll be printing it in the next few days.
