Dog Collar Air Tag Holder - WEATHERPROOF

So, yet another air tag holder for dog collars! 

What makes this one special and worth your time downloading? Well, for one, it is sized for large dog collars, up to 1.25" (32mm) in width. But most importantly, I made this with the primary goal of ensuring that I can put this on my dog's collar and never have to think about it, whether he is swimming in the ocean, river, burrowing in a hole, fighting with his sister, or rolling in snow. 

I have had this model shown printed for 2 years, it has survived all of that and much more. I have even dropped it in the bottom of a pool for an entire day to test its waterproofing. Obviously, this is not recommended and heavily reliant on your print settings, but it can be done. 

If anyone shows interest in customizing the lid with the name of their dog and enough interest is shown, comment on the design and I can either upload the CAD file or make modifications for different collar sizes. 

Key notes, 

This print uses 4ea 3mm x 12mm screws, washers optional. 

Medium threadlocker on the screws is HIGHLY RECOMMENDED. If you don't have, a dab of superglue works well also. 

The “base plate” is sized for a standard 3mm heated insert 4.5mm height or shorter. 

If you do not want to use a heated insert, you can assemble the airtag holder and with the screw inserted, you can fill the cavity with superglue or epoxy. Threaded inserts are extremely recommended.

There is a ridge and a hollow in the parts labeled “lid” and “Bottom Seal”, that is deliberate, take your adhesive of choice as long as it is non ridged and WATERPROOF (gorilla construction adhesive, bathroom caulking, E2000, etc), splooge the glue into the recess in the “lid”, place the airtag inside, and stick them together. I tried this with a TPU gasket, but glue works soooo much better and easier. The slight recess on the sides of the assembled unit are for using a screwdriver to pry the top and bottom apart for changing the battery. 

Lastly, print SOLID, and highly recommended printing something heat resistant to keep it from getting soft in the summer and give it a bit of impact resistance. Model shown is PETG.
