Update: after rechecking the scale it appears to be closer to 1/10 scale, possibly a bit larger. Update: 11/23/2017 Added spark plugs, LS3 coils, Coil boot and spark plug boot. Coil Boots may need to be enlarged depending on your printer settings. Spark plug boot is incorrectly labeled. The 90-degree boot goes to the plugs as seen in the pictures. 1/10 scale Camaro LS3 motor. This is a scaled-down version of ericthepoolboy's 1/3 scale motor. The 1/10 scale down was initially done by Novel Mutations and redesigned by me to use 623 (10x3x4mm) bearings and 1.5mm screws. Screws can be sourced from www.rc4wd.com, ebay, or amazon. Most of the 1.5 screws I used were 1.5x 3mm (covers and surface screws), 6mm (crank bearing caps side bolts and crank spacers), 8mm (crank), and 10mm (flywheel). Bearings were sourced from https://www.banggood.com/10pcs-623ZZ-3x10x4mm-Ball-Bearings-Shielded-Radial-Bearings-p-1049663.html?rmmds=myorder&cur_warehouse=CN. 1x2mm Neodymium magnets hold all the parts together. I found them on ebay. The drive motor was sourced from an old HS-645 MG servo I had lying around. The drive gear is simply pushed on with a little CA glue. Cams have to be printed with full support and bearing mounts need to be filed and sanded when done for a flush fit. I used #18 brad nails and CA glue to assemble the cam. The Air filter is printed out of TPU and is secured with an indent on the Air filter throttle body. If you're going to use PLA, you might have to file off the indent on the air filter. This build is not easy. Expect to file, sand, shave, alter, and drill to make this build a working build. All the lifter holes need to be ported, and the push rod holes need to be sized according to what you're using. The pistons and cylinders need to be sanded smooth.
