A V4 engine model with moving parts and a few artistic add ons. The model demonstrates simple engine movement with extra visual features.

notes

• use v4 engine READ ME.txt - it helps
• All holes are 3.1mm for M3 bolts
• This print requires a lot of print time, material and 32 M3 x 10mm bolts
• May require a little sanding/cutting and use of hot glue to keep rods in place
• Chamfer has been added to a lot of edges to combat elephanting
• Assembly is pretty straight forward but order should go bottom engine block – central drive parts – crankshafts & connected parts (piston, connecting head & arm) – top engine blocks – exhaust module – air intake
