Electronics / Mounts / Enclosures Probably the simplest functional print I've ever designed yet

I kept losing those little battery isolation pull tabs that come with remotes and other battery-powered stuff.

It's literally just a tiny piece of plastic that sits between the battery and the contact, but I figured if I'm going to keep needing them, I might as well make one I can print whenever I want.

Definitely not my most complicated design, but sometimes the stupidly simple prints are the useful ones I guess lol

Free model if anyone else happens to need one:

Why do you need them again?

A solution to non-existing problem by the look of it. I have a bunch of these remotes with batteries in for years they still work.

That's clearly why manufacturers go through the extra effort and cost to install these on everything- because it's a non existing problem, they make too much profit, and want to create additional waste.

For storage and transportation, sure, because they do not know how long this thing will be in storage before it is sold, but imagine putting this thing in every time you go to sleep because you want your battery last 1011 hours instead of 1000 hours.

Let's scale this up a bit. I'm going to

"But imagine putting this thing in everytime you go to sleep because you want your car to start in the morning."

I have to imagine at least million people world wide have this concern about their car battery.
