Playing around with Fusion 360's T-Spline forms: a sculpted version of my juice box holder. The handles have been modified to get rid of the need for support.

Updated: v2 is done as a single form, with more aesthetic handles. Still no support needed.

Updated: v3 is done in a way that gets rid of the need to patch holes on the interior, leading to a smoother wall.

Instructions

I don't know why Fusion 360's export to STL lays it down on the side. Use your printer host's plater to stand it up before printing.
