I printed a bunch of these out of TPU and they’re awesome. For the perfect fit with TPU reduce X and Y to 96% and set Z to 98%. It’ll have a nice snug fit and you won’t have to worry about them randomly falling off in the field.


I've been using these for a while. They're just fantastic! I printed tons of them and give them to all my friends too. Everyone loves them.

A little hint; If they don't fit snugly enough put them in hot water for 5 seconds, take them out, and gently squeeze the sides in. The warm water will make the plastic soft and allow you to reform it a bit. Immediately put it on the XT60 connector and it will firm back up as a perfect fit.

That's great to hear!!! Thx for leaving a nice comment to! enjoy using those safety caps!!

Check the remixes, Nagato made a storage version!

Really good! I'd also consider a matching design for a yellow "Store Charged" cap!

for XT30 scale to X 64.6% Y64.6% Z 70%

I found scaling to x,y of 62 and a z of 74 fit the xt30 perfect

thx for sharing this!!!

For anyone who gets an ill fitting result with PLA...you can easily take a torch to printed parts and lightly fan them and make them less or more snug.

Made a bunch from the 11-10-16 files in PLA. They fit great on Turnegy batteries. I don't bother with the full/empty ones. I just print green ones for full and red ones for empty. I suppose yellow or some other color could be storage.

Nice, thx for letting me know!! if you look down in these comment someone his friend remixed one for storage! :)

Hi, congratulations, fantastic caps...
Can you make this cap for XT30?
thank you.

Yes.. Very easy solution, thank you very much.

very nice caps ... thanks ... one variant for storage capacity would be nice :)

I haven't printed one yet, but I wanted to say thanks for bringing an improvement to the standard Red Green caps.

tried your tighter fitting model with a flexible filament and I think you hit it right on the money with that one, nice firm fit.

Great to hear, also there is sometimes a bit of deviation on real and fake xt60 connector what i have noticed!
Don't forget to post "I made one" :)

It fits. but not snug enough for me. They are rather loose and I need to hold them down with tape.

try applying some hot glue on the inside of the cap walls and make it flat with a toothpick, I did this and i now have a nice tide fit and a rubber like feel

They should normally fit perfect, but added a tighter set, check for the latest and let me know!

Which ones files are the tighter fitting ones?

The ones from the last update 11-10-16 are the tighter ones.
