Rubber Band Powered Car Kit — 3D Printed STEM Project

Rubber band powered car kit you snap and glue together in 20 minutes, a 3D printed STEM project for kids and adults. Longshot 2.0 arrives as three flat printed kit cards. Snip the pieces off, glue the axles, snap the walls into the base, then wind up the rubber band and let it go. No 3D printer needed, it arrives already printed. Every piece is labeled on its card, and the QR code on the included build card opens my YouTube channel where you can find the build guide for this car. You can also find the build guide in the embedded video on this page. Good for: - A hands-on STEM car kit for kids, teens and classrooms - A rubber band car science project that shows stored energy turning into motion - A DIY car kit gift for makers and model builders - Learning how a rubber band car works: a big drive wheel on ball bearings, weights for grip and a straight-tracking three-wheel layout Details: - Assembled size: about 8.7 x 5.9 x 4.2 in (222 x 151 x 107 mm) - Printed in two colors of PLA across three kit cards - In the box: 3 printed kit cards, 2 x 608 ball bearings, rubber bands, M5 nuts (weights), super glue and a build card with a QR code to the video - You'll need: flush cutters (or small snips) and scissors - Build time: about 20 minutes The kit includes super glue, so younger builders should have an adult help. A note on the wheels: the photos and build video show solid wheels, but your kit ships with the new spoked wheels. Same size, same bearings, same build steps. Here's why we switched: - Lower price: the spoked wheels use about half the plastic of the solid ones, and those savings go straight into a cheaper kit. - Faster off the line: less weight in the spinning wheels means the rubber band spends its energy pushing the car forward instead of spinning up heavy wheels, so it accelerates harder. - A lighter car overall, with the M5 nuts still adding grip right where the drive wheel needs it.
