IKEA GRONO led-strip upgrade

This is a custom lid for the decorative and low cost ikea lamp.

I have a working version, but it is not perfect. You can print + build it, and you can be proud to it, but if you a maximalist you probably want to work on it a bit.

If you want to improve it, pls give a [PR on github](https://github.com/tg44/3d-tools-and-things/tree/master/ikea-grono-lid) rather than just remix it here!

Things needed to build my version:
- Wemos D1 mini (banggood or ali-express will help you out) 1.5$-3$ (I prefer the slimmer version in general, but this build with the bigger chip, the PCB has the same size)
- LED strip, I bought WS2812BECO 1 meter, 144Led/meter ~10$ (but you will use only the half of it)
- the lid printed
- An Ikea Grönö lamp from ikea ~10$
- 5cm utp cable (or at least 3 small cables)
- basic soldering supplys
- probably some small zipties
- a long usb cable
- usb charger / wall adapter (5$ from china)

Total cost for one lamp ~25$
