PKSW Ornament – Final Version

After two full redesigns, three rounds of print testing, and completely re-selecting materials, the holiday ornaments were ready. A short batch of print runs was enough to build ornaments for the handful of friends and family we want to gift them too.

The final print runs took a bit under 24 hours, but overall I’d estimate that I spent 10+ hours designing and revising the ornament model, and 35-40 hours in printing time between the drafts and final prints.

Things I learned:

  • It’s hard to get repeatable, high quality PETG prints without a lot of tuning and trouble shooting. It’s far easier to select a filament like PLA, which will result in much more reliable print quality.
  • For snap fit parts even small increments in layer size can have a large effect on the outcome: at 0.35mm layer size these ornaments take brute force to fit, while 0.20mm layer size results in clean, snug, snap fits.
  • TinkerCad will get non-responsive really quickly when building models with multiple complex positive and negative space groupings.
