But : having a small, portable, autonomous servo tester, to determine the "neutral" position of the servos, check the direction of movement and their amplitude, correctly position the flap in the final assembly of the servo, etc...

Main case - 3D printed with Arianeplast's metalized black filament, 2. Lid - 3D printed with Arianeplast's metalized black filament, 3. In operation, 4. Access to the charging socket, yes, you have to recharge the battery from time to time ;), 5. LED during charge, 6. LED at the end of charge, 7. The heart of the gadget - half of the tester, the battery in its holder, the electronics soldered on a prototype PCB, M/A switch, double thickness of adhesive foam to "stick" the tester against the case once the electronics is screwed in, 8. What's left of the tester (the 4 screws are hidden under the blue label, delicate detachment!), 9. Some components, and 10. Everything in place "before closing";) The 6 screws for assembly (4 for electronics + 2 for lid) are M2x8mm. ...and for those who fear warping... I offer the main case with the "pads" to be removed (important precision) after printing ;).
