I had a chance to practice 3d scanning so I sneaked in my 36’’ evo underneath a ‘‘romer arm 3D laser scanner’’. It’s a high precision scanner that gives high accuracy results, end file has to be put in geomagic to sort the point cloud and in the end you get pretty good result:
Ignore the gray surface, that was me trying to make case arround it. Also there where lot more pints, I just simplified the shape to increase performance.
My conclusions from entire experience (was building case for first time), quite time consuming (building plug from scratch would’ve been twice as fast) but worthwhile I could predict lot more things before 3d printing the mold and in my instance where I tried to squeeze in 12s4p p42a it saved me a 2nd mold, for such a complicated deck shape like evo it was worth the time scanned. For simpler flatter decks a rough measuring would’ve done it just as well. of a job. Sadly, didn’t had time to make photo scan of the deck to compare it to photo 3d scan method.
IMO wouldn’t do 3d scanning for motor mounts or any other 2d shapes, not worth the time or the effort, it’s way faster to just measure it out, print it on paper to confirm the dimensions and go on from there. You will have to do multimple prints to confirm it’s a snug fit for a 3d print anyway.
