This Double-Click nesting case holds 18 micro sd cards and 1 micro sd card adapter and 6 polar pro lenses. The polar pro lens caddy is lined with a non-scratch felt and has a perfect fit. There is a gap at the back of the caddy while inside the case for a small lens cloth. This fits the 33.25mm polar pro lenses so PLEASE BE SURE YOU DO NOT HAVE THE OLD POLAR PRO LENSES AS THEY WILL NOT FIT. (SD CARDS AND LENSES NOT INCLUDED) Original design credit to bgill via thingiverse.
