Party Cracker (fun party favor!)

Overview

These party crackers are a fun way to give guests party favors, decorate place settings, and are sure to make any party memorable!  Not only is there plenty of space inside to hold candy and small toys, but there's an added twist with the self-opening/closing threads.

I made the design in OnShape and there are a few options to choose from:

• Single Color
  • Original version
  • More threads modified version
  • Tighter fit modified version (only recommended if you find the original fit to be too loose)
  • More threads + tighter fit modified version
• Multi (two) Color - split into the internal and external threaded parts for proper color change 
  • Same versions as the single color option

Update on 1/20/23: Added individual part STL files

Update on 2/25/23: Added the “Fancy!” version, which has the swirled threads on the outer body of the part.

Update on 5/7/23: Added the “fixed” versions, which has doubled the thickness of the connections on either end of the knot.  Should be stronger than original versions but will be affected by scaling of the model.

Printing

I printed the single color original version in Prusament Viva La Bronze, as well as the multi-color modified version with more threads and a tighter fit on the Prusa i3 MK3.  I've included the original STLs and g-code for all printing options, but let me know if you'd like any other versions and I'd be happy to make them!

If you re-slice, I recommend just applying “support on build plate only” and orient the parts similar to the provided g-code.
