Canon LP-E6 battery holder with SD card slots
A camera-bag organizer that carries three Canon LP-E6, LP-E6N or LP-E6NH batteries, the 38.4 x 21 x 56.8 mm pack shared by the EOS R6, R6 Mark II, R5 and 5D series, alongside four SD cards. Battery bays are 39 x 21.6 mm with 0.3 mm clearance and a 45 degree thumb ramp so a pack tips out in one motion, and the SD slots are 25 x 2.8 mm with a 2 mm spring lip so cards cannot fall out when the case is upside down. A sliding lid on 1 mm rails covers everything, with a 3 mm loop for a lanyard. Print it upright with 1.6 mm walls and a 2 mm floor; the lid prints flat.
Generic battery caddies are cut for AA cells and ignore card storage. Describe the batteries and cards you actually carry in SpeakCAD, preview the holder in the browser without paying, add CFexpress slots for an R5 in the chat and download the STL.
