Another engine for 3D Printed Marble Machine https://youtu.be/92JgI5a3J4A After I made the wonderful Marble Machine #3 by Tulio Laanen (https://www.thingiverse.com/thing:1385312 ) I liked the idea of making an electric motor for it. Of all the things I've done so far, I liked Brannnt's project the most (https://www.thingiverse.com/thing:5357447) . However, having done it, I discovered that my gear motor is not attached to its housing and falls through it. I had to completely redo the design by making a gear motor mount. For one power supply, it was converted to two AAA batteries that are more acceptable to me. Additional parts required for assembly: 1pc mini gear motor GA12-N20 3v 30rpm. https://www.aliexpress.com/item/4000274747864.html 1pc Micro switch ss-12f15 https://aliexpress.com/item/1005001750221821.html 2 pairs of battery contacts https://aliexpress.com/item/4000245292258.html 2 pcs AA batteries 2 screws 2.5x13 rigging.stl - designed to help in the correct installation of the lower pad. It is necessary to solder two contacts as shown in the photographs. Behind that side, slide them into the bottom of the battery compartment and turn them into a working position there. The rest of the installation can be seen from the attached illustrations. Printing was done with PETg plastic nozzle 0.4 layer 0.2 without supports. All details are published in print orientation.
