.. The quality of those resin prints is stunning.. well done!
I have been progressing "ok" in comparison with my powered 3d printed LGB decoupler.. Your print quality makes my home build FDM (based on a shapeoko router) look very crude..!
The initial PCB's arrived a week ago and after soldering on the SMD processor and driver IC's (and fortunately getting the answer right to "Which way round do they go??") .. I have now programmed a couple for testing.
I have assembled this one with the ICP still attached, so that I can tweak the software, but in a "final" version the side of the enclosure is closed and you cannot see the board.
Good thing is that I can report that the the tiny linear stepper gear can produce about 8oz thrust (I am metric but my spring gauge is older!) and takes about 300mA from 5V when working. This enough to break the pull of the "magnetic" hook spring closure and push both its own hook and any attached hook down - provided they do not get stuck on the internal "lip".. But the "decoupling waltz" should take care of that.
