The solution is to shift the X-axis holes by 1–2 layers along the Z-axis.
And that seems to work quite well, when printing from ASA/ABS at least.

What if we make the grip feature horizontal? This almost works — the only problem is that the slicer prints all the overhangs at once, which causes some pretty severe sagging.

Which type of grip features can we print on the sides? How about two fins on each side?

This might work at a larger scale, but at this size the grips will just snap along the layer lines.

First, how do you make something that holds well and doesn’t degrade quickly? You add flexible fins. There’s a great video from Slant 3D about this: https://www.youtube.com/watch?v=yzg_NXM-NRs

This works great on the top and bottom, but what do you do with the sides? You can’t print those angles on the sides.

No problem — let’s just use a cube net. We also add some angled pins for a reliable hold.
