Description
A flathead engine, also known as a sidevalve engine is an internal combustion engine with its valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine.
Printing and Assembly
The parts should be printed on a smooth build plate, not textured.
If possible, avoid elephant foot.
I printed the model on a PRUSA MINI, with PLA+ filament, layer height 0.15 mm.
I use Hard Plastic Glue where necessary.
For assembled and exploded views, use .stl files 00… 01... 02… 03… (do not print).
Printing and assembly in alphabetical order (A1 → J1).
Printing tips are available for many parts.

Dimensions: 89 x 98 x 149 mm.
Weight: 0.14 kg.
Metal parts
To join the cylinder to the crankcase, two metal 70 mm M5 threaded rods are needed, and two M5 nuts .
Two coil springs are needed for the valves, 10 mm width x 15 mm height. Wire thickness 0.6 or 0.7 mm (AliExpress).
