Baby crib automatic swing drive-unit / Babywiegen-Schaukelantrieb

I'd highly appreciate it if you could post some pictures! In order to soothe our daughter, I've designed this drive to swing the crib back and forth. The motor used is a JGY-370 with 6V and 40 RPM. It's intended to be powered by a USB-powerbank with 5V, which will result in about 33 1/3 RPM, roughly one back and forth in 2 seconds. There isn't any hole for the cable yet, you might want to drill it according to the cable you have. You need to use some bolts to fit the motor into the housing (M3), as well as to connect the arm, hinge, and motor. I added some washers in-between to reduce friction on the plastic. The pictures show the first revision of the housing, which was a bit too long. So to test the mechanics, I cut off some part of the plastic. (This is why it looks a bit rough at the left edge.) The motor I ordered comes with a driver-unit, which allows me a speed reduction of 1:10. (Unfortunately, the motor hasn't yet arrived from China due to Chinese New Year) It can be found here: https://de.aliexpress.com/item/Bringsmart-JGY-370-High-Torque-Worm-Gear-Motor-12-Volt-Electric-Motor-Reducer-6v-Engine-Power/32841473974.html?spm=a2g0x.10010108.1000016.1.a8be50faBPyPxn&isOrigTitle=true (package four and "other ( -V -RPM)") After I receive the motor & driver, I may revise the housing to fit both. (Currently, only the motor is included.)
