EUDAX 6 Set Rectangular Mini Electric 1.5-3V 24000RPM DC Motor with 84 Pcs Plastic Gears,Electronic Wire, 2 x AA Battery Holder,Boat Rocker Switch,Shaft Propeller for DIY Science Projects

I'm not a Warhammer guy and had no idea what that meant - but Microsoft Copilot cleared it up for me. Except for the batteries, screw eyes, the block of wood, the paint, and the strap holding the paint, the parts are all from this kit: https://www.amazon.com/dp/B077WWS63B I didn't build it with a plan - I just did it on the fly. I've just drawn this up in draw.io. Please forgive my crude drawing skills. I screwed down the battery holder and then the motor bracket next to it. I attached the gear to the motor. The gear doesn't actually work as a gear, but of the parts I had, it fit what I needed it to do. It has holes around the edges. There are 2 parts that I'm unsure of the name - I'll call them rails. They're smooth on one side and have serrations on the other side to fit a gear into - but I'm not doing that in this project. I attached the rail to the left gear into one of those holes using a rod/axle that came with the kit, then I attached another rail to that rail via another rod/axle. At this point I needed to make sure the 2nd rail stayed level so I used screw eyes to keep this rail from bouncing around too much. It still does bounce around too much, though - a better solution would be rectangular eyes for the rail to slide though - something just big enough for the rail. Remember to keep the serrated edge on top so they're not grinding in the screw eyes. Then I just attached a bottle of paint to the end of the rail with a silicon band. One thing to keep in mind - these 3-volt hobby/toy motors are VERY weak. They spin fast but have practically no torque. You have to keep resistance at a minimum. Since posting this, I've been working on trying to build a better one, using gears as gears but I keep running into the issue of torque. If there's too much resistance or weight downstream for the motor to move, it bogs down and stops.

This is the kit where all the parts came from: https://a.co/d/0dQSz6jA I bought it in 2021 and I don't even remember why. It might have been after I bought a millennium falcon model kit and I was thinking about motorizing the ramp. The bottle is strapped on using one of these silicon bands: https://www.amazon.com/dp/B0D4QXKXMR?ref=ppx_pop_mob_ap_share Edit: And FYI, there's not a lot of context on that Amazon listing for the motors and gears of what you can actually do with it but this listing for a similar kit has some product images of projects built with those components, popsicle sticks, and other odds and ends: https://www.amazon.com/EUDAX-Propeller-Electrical-Engineering-Education/dp/B0CTKKV7J4/
