This is a MK2 version of my original BT-60 Av bay, while it might look similar to the original this is effectively a clean sheet design.
Why you might ask?: Well the 1st version worked well as a proof of concept and in flight preformed great but from a 3d printing point of view was rubbish, it required way too much support material and once printed the suport material was hard to remove without breaking the part.
The New design uses all the same hardware as the original but the printed parts are now much more printer friendly and tolerances adjusted slightly. You still need to print it with support from build plate because of the step out to the exterior body tube diameter but importantly it is only a small amount of support and very easy to remove.
This is designed for a Eggtimer Quark using 2.5mm power jack as a switch and power from 1 Cell 250mAh LIPO (The sort used in micro quad copters like the inductrix)
