Inspired by samaras/helicopter seeds, I designed a projectile and launcher. Don't expect it to shoot really far, but in my testing it usually gets 10 to 20 feet before fluttering down. Your mileage may vary, but so far, it seems very satisfying, and my kids really love it. https://makerworld.com/en/models/2681080-helicopter-seed-and-launcher#profileId-2969265 #Hostedbycreator #Springplaychallenge #Contests(Edited)

When I was making the gear chain for my excavator, I found it very fun to play with. I decided to make a fidget version of a gear chain. When you spin the small gear on the top once, the gear on the opposite end will spin fast #Contests #Pieksekisten #Hostedbyu(Edited)

You might be wondering why anyone would bother 3D printing a wall mounted bracket for a spool when you could just run two screws through the spool and call it a day. There are actually a few solid reasons. I came up with this idea because I get a lot of cardboard spools, which aren’t strong enough to be mounted to the wall using conventional methods. When I thought about it more, I realized they also have the added benefit of being very easy to remove if you want to take your cords with you.#Contests #Hostedbycreator #Filamentrecycling(Edited)

After more than a month of engineering, testing, and refining, I’m thrilled to share my fully 3D‑printable RC excavator. With over 70 printed parts, it’s definitely a project, but I’ve put a lot of care into creating a detailed, step‑by‑step build guide to make the process as smooth as possible. I’d love to hear your thoughts, and if you print it, see photos of your make.
