Schottky Barrier Rectifier Diode, DO-41Small Signal NPN Transistor, TO-922 pin Molex connector 2.54 mm spacing | | | | | | Tayda | A-2939 | | | | | R1, R2, R23, R24 R3, R21, R27, R28 R4, R6, R7 | 3 pin Molex connector 2.54 mm spacing | | R16, R18, R26 | 3 | 1 C10, C14 is a consideration. FDM printing is the cheaper option but won't reproduce tiny smooth curves all that well. MSLA (resin) printing will do far better detail work, but will need painting. Could be glued on with CA or hot glue, if the PCB is used. In loop.
