My pleasure Damon.
Not to much to show for an afternoons work today but editing in cura, printing and making tiny parts fit correctly take time.

These intakes have proved problematic but I think I'm there now but for maybe a slight reduction in height once I'm sure of the air cleaner pipe work heights

I may have to lower the air intakes but not sure yet as I have no dimensions to cross reference, it's all guess work and if it looks right then maybe it is right

Once the engine bay cassette is in place everything above the rockers must be demountable, I have to build it all on the bench, dismantle and reassemble, once the engine is slotted in for the last time it can all be bolted in place.

Editing in cura and printing the air cleaner drums and drum tops today.
A tip for those like me that are not familiar with creating stl files from engineers drawings, collect basic stl files from the various sites on the internet which are often free, simple objects like cylinders, discs, square boxes, rods and anything that looks interesting, then using your imagination and Cura edit those objects , you will need to join pieces together to make more complex parts like engine blocks and pipe fittings ect.
Cyno offers a very strong adhesive for pla, once bonded you will have difficulty separating those parts. Drilling and tapping works well to.

The base of that right angled water fitting that I made yesterday is actually the thermostat housing. That's what the bypass pipe is for.
