3D printed, 1/35 corrugator
Frank3k:
I wanted to make some 1/35 scale corrugated roof panels (8 feet/2.4m long) so I found the cross section of a standard panel, traced and scaled it so the period of the "waves" were correct for 1/35 then made it 2.74"/69.67mm long. I printed the results today in PLA and it worked well enough for my purposes.
The two panels. The top half aligns the bottom half. It's in bright orange PLA, because that was the free filament that came with the printer and I still haven't used it up:
Two halves together. I had to mark the correct edge, otherwise the corrugations could be 90 degrees out of phase :
Here's an end view. The curves do line up - the two parts are slightly separated here:
And the results:
The top one was made with with thicker aluminum crafting foil. I don't have a vise, so I had to step on it to get the two halves to meet. The lower one is with kitchen aluminum foil, which was easy to corrugate. I also experimented with running a mechanical pencil over the craft aluminum foil to push it into the corrugations, then squeezed the top half. That worked as well.
I used PLA instead of ABS because I felt PLA would stand up to pressure without deforming.
The panels can be trimmed to size and painted. Not bad for 90 minutes worth of work (about 20 minutes looking up corrugated panels and designing it and an hour to print, plus a few minutes to test.) The kitchen aluminum foil version looks a little deformed because my cat Felix decided to play with it.
Old Wombat:
Cool! 8)
Any idea how it would go with coffee tin foil? ???
ChernayaAkula:
Neat! :smiley:
Frank3k:
Guy, the regular kitchen aluminum foil I used is 0.02mm - 0.03mm thick and the craft aluminum foil is about 0.12mm thick. I think coffee tin foil is between those two.
apophenia:
Oh, that is very cool!

And, thus, a new weathering technique is born :smiley:
