I had a Heltec T114 lying around and few batteries, so I designed this.

Exact battery that fits is 3.7V 3000mAh 103665 , link https://www.aliexpress.com/item/1005005031129301.html
The switch is SS12D00, link https://www.aliexpress.com/item/1005005633418066.html
I used 4 screws M2.5 x 6mm (it can fit up to 12mm I believe) length countersunk screws.
Of course, you need also the IPX (U.FL) to SMA connector , link - https://www.aliexpress.com/item/1005008815359328.html , I got the 5cm ones.
I used organic support from everywhere, in Prusaslicer. That worked pretty well.
