I hated the fact that I had to carry my Panasonic 45-175mm lens separate from my inspire 2 case (including the X5s camera) as there was just no place to put it inside the inspire's case rattling around inside the case during transport.
so I looked at the lid of the case and found there is quite a few cavities that is empty that can be utilized to hold things with the appropriate brackets / mounts
so designed a few, and glued them into the lid with hotglue to keep them in place. The design uses a holder with velcro straps , to hold the panasonic 45-175mm lenses on its side, with enough space to clear the X5S's box inside the inspire case, and to stay clear of any other items in the case, including the inspire. To use the lense, simply remove the lens by loosening the velcro strap. works great and firmly holds the lens in place until you need it. see the pics for more details.
Printed the holder in PETG with 100 infill modifiers where the straps go through the holder
