This marble run kit was very enjoyable to build. It also functions better than most due to it having actual hardware for the moving parts versus wood pieces scraping against each other. Where to get it: www.amazon.com...
I've never heard of them either but I like that they don't rely on just all wood parts. The plastic pieces make things work so much smoother than the standard wood marble run kits. 😁
I hope I make it far enough lazing that I can start designing these. It all depends on if my products sale. Just about to open an Etsy shop to start, then soon after expand to other sites- starting with 1:64 (hotwheel scale) miniature houses. Want to also do layered mandalas, marble runs and a whole lot of other scales of miniatures up to about 1:12 (Barbie size). Nice video, I love these things :D For 20 Dollars, that's very cheap for what you get- seems like a great deal. I wouldn't be able to sale anything like this for any less than 50-60 just so that I can make a profit and justify designing it in the first place- shipping will be pretty standard though so that part will be faster. They probably use a fast high powered laser though which really helps keep costs down.
I wish this did come with a motor. That piece does look like a pulley. I wonder if it was originally intended to be motorized? I will say though that this one has the smoothest crank operation of any of these that I've built in the past.
For the next time if you get a foreign language try the translate app. from the Apple phone. I tried using it on the screen shot that you filmed and it translated it
I have the Google Translate and it works really well for stuff like this. Thankfully I didn't really have to use it. The pictures in the instructions were pretty clear. 😁
