About this 3D model

I tried to locate these replacement parts but found them extremely difficult to get hold of as they are classed as rare the only original plastic ones i could find were around £55 a set so i decided to try to make some. It was designed in 2 halves to avoid the need of supports so both halves will need to be stuck together using epoxy/araldite or similar to ensure strength. Included a version that is joined together for printers that are capable of printing it whole If printed in PLA will melt if using a high power brushless motor so its advised to use ABS I will be making other parts for the HPI Sprint / Sprint 2 so it may be worth checking out some of my other designs if you own one and want to reduce repair or replacement costs drastically.
