FULL CAR PACK NOW LIVE! - https://www.cgtrader.com/3d-model-packs/kyosho-lazer-zxr-zxrr-full-car-pack-with-some-mod-partsThese parts form the main gearbox for the Kyosho Lazer ZX/ZXR.You will have to play about with positioning in order to get the strength where its needed.Holes where a screw passes through will need to be drilled out with a 3.5mm drill bit. Other screw holes are set to 2.7mm for a self tapper but dependant on the filament used you may need to heat the screw a little to prevent cracking. I usually put the screw in boiling water for 2 minutes and then carefully screw it in. Once the threads are cut you should be able to back the screw out and put it back in with no issues. I printed this in CC3D polycarbonate and didnt have to heat anything at all but when I printed it in ASA I had to heat the screws. That said, ASA although not as strong as Polycarbonate does have almost the impact resistance of ABS. Choose your filament wisely.These parts have been tested and now are interchangeable with all original parts.Check my other files i have for sale and you will see its possible to 3D print an entire Lazer ZXR from these files.I will upload a video to YouTube pretty soon and link it here - https://youtu.be/A3WvQG3Msh0?si=Ly0Qf-x2fp1rYVGS
