This is a holder to attach a 100mm X 100mm Cokin filter to a DSLR camera.

The clamp fits a lens OD of 83.5mm but will likely fit plus or minus 1 or 2mm. It provides a very secure attachment. The filter holder also provides a very secure fit for holding the filter in place.

I have included the AutoDesk 123D design files so you can modify the design.

Also included is a box to hold the clamp ring and filter holder.

The clamp ring could be used for other accessories such as a large lens hood or other types of filters.

Enjoy!

I used ABS as the camera equipment is often stored in a car where temperatures can get too hot for PLA.

Add the hardware
(3) 3mm X 30mm bolt
(3) 3mm nuts
(2) 3mm wing nuts

There are recesses for the nuts to hold them in place.

Gently slide the filter into the holder and take some pictures.

I used AutoDesk 123D to design this. The tricky part was getting the clamp to seal out light by having an overlapping part. Also a few iterations were required to get a good fit with the filter.
