printed Nipkow Jigsaw
Posted: Tue Jun 27, 2017 5:23 pm
I'm experimenting with 3D-printing a Nipkow disk. I've created a 'jig' which is 1/8 of a slice of a disc. It should snap together with similar pieces, using a kind of dovetail/jigsaw connection - hopefully snap-fit. I've also added a gazillion holes - these are a "single" spiral of 32 holes, but all holes on the 1/8 slice at the same time. The concept is that you print 8 of these, snap them together, and then cover the holes you don't want. They should all be in the correct places for a "complete" spiral with appropriate holes covered.
Anyway, thought it was worthwhile seeing how it goes, so it's printing now. I expect the snap-fit to be tricky because of the printing inaccuracies, but I can pare down the edges with a scraping blade and it might work. I'll try and update once the print is done - I'm doing two slices as you see here - but printed separately of course.
