Is CPE sturdy enough?

I had to play with it a bit, but if printed the was it is shown in the first picture, it comes out fine. I did the larger size. There is some support included in the model. I added supports so there were no gaps, otherwise I got gaps and drips. I was able to copy and print 5 at a time. After printing I hit the edges with a dremel, then used 2 drops of super glue per shuttle. I made 125 for a tatting guild. The ladies were quite happy to get them.
I used simplify for a slicer.
Thanks for the pattern, I did attribute it.

I attempted to print one of these. I'm having trouble with it. I'm using a 0.4mm nozzle with ABS filament. I have a couple of questions...

  1. Should I print this thing laying flat in pictures 2 and 3, or sideways as pictures 5 and 6?
  2. What should I set the infill density? I have it set at 50%.
  3. Which slicer yields the best results?

Thanks,

  1. On sideways.
  2. Infill density doesn't matter that much. I used about 25%. Also you will need raft and support.
  3. I used Makerbot desktop to slice it with a customized profile. I confirmed that CURA works as well. Refer the settings below to your slicer's setting:

Printed this in PLA. Guess my printer needs more calibration. It broke while I was trying to assemble it. :(

PLA is too brittle to use. I recommend ABS.
