This is a compact holder / clip for the Camranger that fits in your camera or flash trigger hotshoe. The Camranger is held in with two small tabs that slide into the slot between the top and bottom sections of the device. Slide the clip onto the Camranger from the top (where the indicator lights are) as the tabs won't get past the micro USB port or on / off switch on the side.
I designed it so the tabs themselves only apply a small amount of pressure so that it doesn't cause the bottom cover to come off and the main body of the holder fits snug against the Camranger to help hold it in place.
Be sure to check the print for any rough spots to keep your Camranger from getting scratched up when inserting and removing. I also recommend putting a piece of clear tape over your serial number to avoid having it scrape off from use.
I'm not fully clear on the interpretation of the CC-A-NC license so just wanted to say you are free to print this and use it on the job (paid or otherwise), just please don't make prints to sell or offer the STL for sale.
If your printer bridges well and you print it on it's side you won't need supports. If your printer doesn't bridge well or you just want to play it safe you will only needs supports under the shoe block which won't add much time nor additional filament use.
