Gears are indeed cool. If you’ll look closely i have reinforced it with a laser cut acrylic flat bottom for making sure the connecting rod pin wont bent it (and if you look even closer you will see I have lasered recessed drill holes for the bolts nuts - so cool) and also for having it rotate on another acrylic rim bolted to the wood base for as friction-less operation as possible. laser cutters and 3D printers goes together like… Arts & Crafts.
