Pinhole Camera Lens
Check out the beautiful red rings on this pinhole camera lens!
I made an L series wide angle pinhole for my canon last night with my makerbot. had some leftover super red plastic in there when I loaded the black. It put down 2 rings of the red before the black started coming out.
Designed by thingiverse user chriswoebken, this is a nice print by tmo-photo! Check out all the things he’s designed on Thingiverse. Lots of great photography stuff!

sure you can. fill the barrel with red get it nice and hot then pull it out and put black in. then start the print. if you use the raftless plugin and print from the inside out you can pretty much do this every time. I have made 6 of these now, they are not perfect but damn near, a little touch up with black paint or a sharpie and you are good to go. you cant transition from dark to light ABS (takes much much longer to clear the dark out) but lighter plastic to dark plastic works really well
makerbots are not about perfection, they are about good enough. and being good enough is by no means a bad thing. it has radically changed the way i work, tinkering with the machine for weeks or months to get that perfect test calibration print is really not what this is all about for me. that is exactly what it’s about for a lot of owners out there and more power to em. i wouldn’t have been able to plug crazy numbers into skeinforge not knowing what i was doing at all, then turning it on and just having the machine work. without these truly dedicated brilliant people i would be totally lost.. getting it good enough and cranking out an entire makerbot frame in 4.5 days is what its all about, charging ahead and making cool things that would just never had been possible for me 2 months ago.. its not perfect but this thing isn’t a 30k$ machine, it makes things that sometimes require some fixing, remelting, bending, drilling, or even reprinting for them to be useful and good enough. printing a half dozen pinhole caps in a night for an afternoon BBQ pinhole party is pretty damn fun.
you can do a lot with some sharpies, a hot glue gun and a makerbot. a lot of it will looks a bit scruffy and “crude” but it just works and its so damn fun.
ps. the entire center section of that pinhole cap collapsed while printing it. when it was done i chopped out the rats nest, burned it with a lighter and smoothed it out with a heated xacto blade. i nearly stopped the print 4-5 times because it was such a disaster. in the end it worked out pretty well.
