Lightweight Loc8tor tag clip holder
Loc8tor tags are great as lost-model trackers if you often fly (and crash!) over crop fields or trees, but they not designed to be swapped between models very easily.
These lightweight 'clips' can be stuck permanently to each model and will hold the tag securely, whilst allowing you to switch the tags between whichever models you're actually flying without needing to find the roll of fibre/LX/duct tape.
The quick-release clips themselves are strong enough to hold the tags securely in normal flight but they are printed in the weakest direction so the laminae will separate with moderate pressure. I could make them stronger by printing them with thicker walls (or by ABS bathing them) but they're adequate as they are in my opinion.
There are three variants in the perimeters of the clip - half-height, three-quarters and full-height. You may want more (or less) protection for the tag itself depending on how you fly.
