Jigsaw Cookie Cutter 2

I printed out the cookie cutter and learnt a few things:

  • It would be better to print upside down because the bottom layer on the heated build platform tends to be squashed and as such doesn't make a good cutting edge
  • The cutter is too small for a good sized cookie (yum, cookies...)
  • The edge at 1.5mm is way too thick and according to a cook I asked, not good for making cookies
Also, a tip to anyone doing printing of objects that have thin walls with a fill in between: print from SD Card! If you ever see a zigzag fill going on in the output of Skeinforge between two walls that translates to a whole load of GCode and the serial link is just not fast enough. As a result, your walls are going to get over full and pudding out. Using the SD Card will give you a zippy fill.

So, now I've redesigned my cookie cutter to have really thin walls. In fact it's 67 layers, one layer thick! Let's see how that prints out!
