Update - working on version 2.1 now!

With 2.0 programming was difficult: I made my own firmware for the STM-32 microcontrollers and added an ESP board for Wifi, With the rotating motion some very low vibration caused to loose my the connections to the ESP boards. 
But I just discovered this brand new product which should solve those issues and should make programming super simple:

That is pre-order and now it says it will ship on November I ordered a month ago while it said shipping on October so it will be a short delay.
I expect to transfer my existing code including web app very quickly to that new platform. USB access is really a gamer-changer here. Those STM-32 programming boards are just terrible.

Some asked me in PM about STL files. Just drop me a PM ... I will send it to you.
