Massive Lego V6 Engine

thingiverse

This thing is still a work in progress, albeit with some questionable progress. I will update this Thingiverse log with better pictures and instructions as soon as I can manage. So far, I've managed to print this working item as you can see from the video, with some post-processing detailed on each part. To get started, you'll need: 6x Block (this needs support, minimal post-processing required beyond removing that support) 6x Conrod (print this sideways, it requires support and will need sanding to achieve a good ball joint) 6x Piston (I printed the top up, so it needed support; some sanding was necessary for a smooth finish) 2x Crank (printed standing upright with support) 2x Crank mid (printed on their side with support) 3x 2 Axle (printed on end) 12x Clip (printed standing on end with support) 4x Half Clip (printed on end with support) 4x 4x1 Tall (printed standing up as normal, no support required) 2x 6x1 Flat (printed standing up as normal, no support) 2x 4x1 Flat (printed standing up as normal, no support) 1x Fan (printed as modelled, minimal support needed?) 1x Stand (printed with low infill to save plastic, no support) I've added a few exploded view images that should help you assemble the thing when you have all the parts (and corrected the number of axles required). https://youtu.be/Qzeq3x_GwpE The issues I've encountered so far are: - The piston to conrod ball joint is stiff and produces most friction in the system, requires more sanding than initially given. - Pistons may need a slight reduction in diameter... - Stand is huge and peels easily due to large flat first layer - Some studs don't link strongly with other parts as desired (I found this especially with the 4x1 Flat which has slightly larger studs now) - The fan ends lack the correct castellation pattern on them, they appear correct but in reality have the wrong number of teeth. I couldn't get Onshape to model what I wanted... As I'm quite happy with my existing one, I haven't touched this project in ages; therefore, I thought I'd link the Onshape used to create it so others can play if they want: https://cad.onshape.com/documents/9e983987f9a9cf60fdcd7618/w/37b954911e52e9490f445bcd/e/f8aeec37bd064d8149fa0032 I'm fairly certain it's in the state I printed it at, but no guarantees are made.
