Hey Guys,

This is a modified Version of an already existing engine from thingiverse. I printed this at 210% Scale. I noticed that its complicated to print the block without supports, so changed some Things and now it is possible to print it with no supports at all. I also added a top end for the engine to cover up one side of the Block. You can put the top end on or off and it fits quite good (if cleaned properly).

My settings for the different parts are:

Bottom end : 20 % infill, 0,3mm layer hight Block: 20% infill, 0,3mm layer hight top end : 20% infill, 0,3mm layer hight (with supports) Crank and Pistons : 30% infill, 0,2mm layer hight (with supports)

I will upload all of my results soon.
