Đế pin LR44 kèm LED và công tắc

I created this battery holder to light up this Easter Egg model: 

 But you might use it for other thing too. All you need is a 15mm hole where you can shove it in.

There's space for two LR44 batteries for a total of 3V.

Any LED working with 3V should be fine.

It's designed for push switches with this dimensions:

I sourced mine from Amazon https://www.amazon.de/dp/B0CZNFQFGF?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

I designed it for and printed it with TPU. I'm not sure if it will work with non-flexible filament too.

Assembly

• insert the push switch in the bottom

• shorten the cathode of the LED and bend the anode 90 degrees

• push the cathode trough the hole in the top of the holder

• bend the anode down the side with duct to reach the lead of the switch

• solder the anode to the switch

• solder some wire to the other lead of the switch to extend it

• bend the cathode and the extension wire in the battery compartment to be parallel to the top/bottom

• insert LR44 batteries (negative goes to the top)
