FULL CAR PACK NOW LIVE! - https://www.cgtrader.com/3d-model-packs/kyosho-lazer-zxr-zxrr-full-car-pack-with-some-mod-parts
These parts usually come in a bag together, parts 1 and 2 make a diff casing that was in the Lazer ZX and ZXS i think, the Lazer ZXR and ZXRR had the ball slipper type that is part 3 but the metal drive cups are pretty much impossible to find nowadays. I have been printing the gear type diff (Parts 1 and 2) and using optima mid internals or Spider TF2 internals in my ZXR's which works with no issues. I havent managed to print these successfully on an FDM printer because i found the teeth to be too shiny and round for the belt to run on without slipping. I use an Elegoo Saturn to print these in ABS like resin and four M2.6x12 screws to hold it together. I put a fair bit of teflon grease on the gears first. Raise each part off the bed and manually add support on all flat surfaces. Please see my other files for other Kyosho Lazer parts, the whole car with the exception of one or two pieces will be uploaded in pieces and there will be a single download with all files as well. I also have other parts for Schumacher, Serpent, CEN, Yokomo and many others that I will eventually upload as I have time. I will be uploading an hour long video explaining some of the Lazer files to YouTube very soon and when done I will link it here. - https://youtu.be/A3WvQG3Msh0?si=Ly0Qf-x2fp1rYVGSI - If you are a Lazer fanatic or vintage RC Lazer racer have a look at Rubrix Racing on their website, they have started manufacturing Lazer parts, all excellent quality replacements and upgrades as of April 2026.
