Universal / modular Nerf Rainbow Catch system for high powered homemade Nerf blasters

thingiverse

These are the files for my design of the rainbow catch system - extremely reliable and catches hard every time. Designed to be 3D printed, I highly recommend 100% infill on every piece. Use this for a solid foundation on your next homemade project! Currently designed for a 1 3/8th" ID plunger tube, and a 1/4" thick 1/2" wide aluminum plunger rod. If I get enough interest, I'll design a version that works with 1/2" nylon rod. Assembly instructions: These are the threaded inserts I use: https://www.amazon.com/uxcell-Female-Knurled-Threaded-Embedment/dp/B01IYWV8Q0/ref=sr_1_2?ie=UTF8&qid=1527422982&sr=8-2&keywords=knurled+brass+inserts To make it, you'll need to print two Spring plates, two catch sliders, and one Rainbow catch. Insert brass threaded inserts into the holes on the side of the Spring plates, and on the top and bottom of the Rainbow catch. Thread a long 6-32 OR M4 screw into one Spring plate, then thread your two catch sliders on top. Place the second Spring plate on top of the catch sliders and secure with two nylock nuts. Slide your catch onto the catch sliders, ensuring it moves smoothly. Slide the whole assembly into your plunger tube and drill the needed holes, securing with short machine screws that match your brass insert's thread size. Be sure to place a spring on top of the catch as shown, and thread two medium length screws into the catch as shown.
