It ended up being a little small. I'll trim the former and use some lightweight filler to hide the seam though.Looks like a good print. Please share how it fits to the boom when you get there. Depending on how you cut your formers the fit could vary a bit. I did 3 different versions to narrow down to a perfect fit for my build, among other changes.

It’s not very far off. That’s a good idea - I should have thought of that...I hope its not too far off. I think to get the best fit you would have to build up until the point you are ready to install these parts then take height 'y' and width 'x' measurements of the part just after the cowling and plug these numbers into Cura to do some non-uniform scaling of the part.

Matagami, thanks posting these 3D printed parts, I've printed all and will be using them on my next P-38. I was wondering if I could post an "ask" ? Any chance you could design a .stl for the entire removable nose ? I'd love to be able to print one in LW PLA and be able to quickly due to a rough landing. I don't have any CAD skills and your parts look great so far. I'd be willing to donate some money for your time. Thanks again
WOW! That was a fast response! I'll do as you mention and print the first half inch and see how it goes. Really appreciate your work! I'll post pics as I get it printed. Thanks so much!
I have a Sidewinder X1 printer so the build volume is not an issue. I have the printer started now, so I should have some results soon. I see what your talking about with the cannons being unsupported when they start printing, only way I can adjust is to increase infill (my lack of CAD skills!) so there is something there, but that will cause the part to be to heavy. If you find a work around, great, if not, I'm not going to complain!
For 1st try I'd say it looks pretty spot on from the pictures. Is the tapered square any good? I think it should handle that little extra nose weight just fine and will probably look great once painted up and in the air. Please post the finished build!Here are some pics of my first two prints. Printed one in regular PLA and one in LW-PLA. The PLA part came in at 112 g, the LW-PLA weighed 67 g, and the original foam board piece is 44 g. I'm sure I can get the part looking even better with a little tweaking in the slicer. The size is pretty darn good, just maybe a hair big on the bottom but it still looks good. I'm in the painting stage yet on the plane so it's good timing to give this part a go. No problems printing the cannons with the adjustments you made. I'll post some completed pics one she's done, Thanks again!
