Pan Tilt Mod for USB C Power

thingiverse

This is a remix of "Pan tilt head" by eltitomanolo, originally posted on 8/9/17. https://www.thingiverse.com/thing:2467743/files I've modified the base to incorporate a USB C connector for powering the servos and, optionally, to power a camera board or anything else attached. The included file is for the base only. All other pieces are unchanged and can be downloaded from the original, linked above. [See EDIT below.] I tied the USB power pins to the red and brown leads from the base servo. That three-wire cable can then carry the servo signal lead and power from the USB to the upper part of the mechanism to power the other servo and anything else mounted there that needs it, e.g. camera board, solar sensors, etc. I used...: "USB Type-C Breakout Board Serial Basic Breakout Female Connector Type PCB Converter Board" from Amazon https://www.amazon.com/gp/product/B09KC1SMGD/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 The holes in the shelf go all the way through. They're only 1 mm but are intended as pilot holes to use for drilling to the desired size, depending on what screws are used. There's plenty of room around the USB connection for the plug on the USB cable and for routing the three-wire servo cable out of the base. I printed this with a 2 mm shell setting to assure the shelf was strong and to provide plenty of stock around the 1 mm pilot holes. EDIT - 6/1/22: I had forgotten that I also modified the arm (OP's name for it), i.e. the bracket that holds the upper servo. I opened the servo pocket slightly because it was too tight to get my servo in. I also shifted the cable slot back to line up better with the wires on my servo. I've added the file for the new "arm" to this post. EDIT 6/3/22: It seems there are at least two slightly different configurations of SG90 servos. Measured across the long dimension, perpendicular to the output shaft, one type is about 22.5 mm and the other is roughly 1 mm larger. There's also a slight difference in where the cable exits the casing. The OP's arm (in the original post) works correctly for the 22.5 mm version; the arm file in this post fits the larger servo correctly.
