Squelching Squigs

Squigs. Sometimes we get them when 3D printing with extruded filament. Usually they’re the result of too steep an overhang in a model; there’s not enough shelf on layer X for the printer to lay down another layer of plastic on layer X+1, and gravity pulls the newly extruded filament downwards.

A squig is born. Small squigs are usually just an aesthetic issue, but larger ones will cause your print to be touched by His Noodly Appendage and then you’ve got a build plate full of plastic ramen. Not good.

I’ve entered into mass production of the Athena Makeover Kit as Faire Play rewards, and I’ve discovered a small problem. Every few prints something on the printer goes to Wally World and the spear’s clip gets all squiggy.

The clip’s strength is compromised and besides, it just looks fugly.

Some of these Athena Makeover Kits are destined for the hands of folks who have never seen a 3D print in their lives. We can’t be giving them a bad impression of the technology’s capabilities.

Fortunately, it’s an easy fix. I’ve updated the clip to be just a little thicker at its junction with the shaft, which both makes it sturdier and eliminates the squig spawning grounds.

I also added a little bullnose between the shaft and clip, because I find 90┬░ angles at transitional edges between volumes to be unlovely.
