I'm heading out to a camping trip tomorrow and wanted to try another way of swapping filters. The Eddgie designed RafCamera filter adapters are nice because it's secure and allows the use of 3x afocal, but for group sharing and using just 1x I wanted to swap filters quickly without all the threading/unthreading.
The design is completely parameterized and you can build your own custom adapter by changing any of the parameters. Then print yourself or send to a hub near you on 3dhubs.com.
The push fit is very secure and the inner splines are made to mate perfectly with the PVS-14 / Envis objective. The filter is threadable into the front.
The pictured storage box with two partitions for two filters is included as well.
Source code is there, it can be copy and pasted to build a completely new adapter for other use cases. Made thicker and longer and with a printed nylon compression ring and nylon compression screw it can be solidly secure for heavier attachments. I'll give examples when I have more time.
The CAD for this was done in 15 minutes and the first prototype printed in 13 minutes. So from opening OpenSCAD to having first version in hand was less than 30 minutes. We live in cool times.
