After spending considerable time printing various small parts in Carbon-PET, I found a few ready made drone platforms, made of perfectly cut/polished carbon fibre sheets. The prices were ridiculously low, so I went for two:

the ZMR250

And the Robocat270

I got them with all the relevant accessories, but due to some weird LiPo battery regulations, a battery was not shipped. I needed a 3S LiPo with a capacity to keep weight low of about 2200mAh. Assembling the KITs was easy, but no battery, no joy.

I had a few 3.7V 1500mAh batteries used in my previous Portable Environmental Monitor project and planned to use 3 of them in series as a quick solution just until I get a proper battery.

Hope to do a first flight soon.
