Summary

I made this from the original source files for the P6*6 120 Film Pinhole Camera. It is scaled at 25% of actual size and I'll be handing them out as give-away swag at the 2014 Seattle Mini Maker Faire, March 23 & 23, 2014.

If you look closely at the prints, you can discern the tiny knurling at the sides and on the shutter extension!

Some concessions have been made to print this so small:

  • First, all interior voids have been filled - sadly, It won't make photographic exposures!
  • The rear surface has been sliced flush to facilitate printing in one piece with a minimum of support. (this is the first design I have ever published that really requires support to print properly.)
  • There is a hole that pierces the mini P6*6, so that you can look at the world through a "pinhole" ...albeit a large pinhole. While it won't actually take pictures, I made a picture through it:

  • No moving parts for the ultimate in reliability!
  • Lastly, there is a handy keyring attachment loop, so that you will always have a pinhole camera at the ready! Indeed, you can shoot photos through the "pinhole" (see the vignette of my toes).

I added the Knurled Surface Library V2 by aubenc as a source. Pardon the oversight.

Instructions

I printed this at 0.25mm with 2 layers top and bottom, 2 perimeters, and 20% infill. During slicing, I got a seemingly-trivial non-manifold error, and Slic3r 0.9.10b seemed to fix it without difficulty.

It prints quickly, and some clever cooling tricks might improve your results - I had some warping issues until I delayed the fan from turning on at 6 layers. If you print multiple mini P6*6's at the same time, the cooling issues disappear as there is time for the separate objects to solidify a bit before the next layer is extruded.
