Keychain - Mazda Rotary Engine (Print-in-Place)
cults3d
Wankel engines were invented in the early 1960s by Felix Wankel, a German engineer. Mazda rotary engines have a reputation for being relatively small and powerful at the expense of poor fuel efficiency. I modelled this rotary engine in last July... the original size of this model is around 600mm... so this time i challenged myself to make a miniature rotary engine keychain with a scale of 1:10... Instead of the simple hole & shaft... can you see that 6 nos. of roller bearing had been added between the rotor and eccentric shaft? For rotary engine enthusiasts... i think you guys will love to have one of this keychain...
