Whirl Punnet

Howdy, wonderful people!

Stacking and nesting prints are always fun, but I  haven't designed a lot of vase mode prints that work that way!

The problem with vase mode prints that sit inside each other is making sure that the inner print won't inadvertently split the outer one by putting differing forces on adjacent layers.  So, that was the aim with this one - robust stackability.

But lets first look at the shape! it's a classic tapered rectangular container, angled nicely for stacking one inside the other.  There are swirly ribs around the whole thing that are intended for snazzy good looks, and to provide a extra of strength and rigidity (as far as vase prints go, at least!).  

As for stacking, though, the ribs play an important role there, by giving the wall an effective virtual thickness.  That back and forth approximates a millimetre-thick wall, in fact.  Those ribs taper off at the top, though, at an angle of 45 degrees, effectively giving a 45 degree plane drawn with back-and-forth lines.  On the outside, there's a corresponding 45 degree angle at the start of the taper, and that then rests nicely on the interior virtual plane at the top when the punnets are stacked together.

And then, just because, there are four smaller versions that fit neatly inside!

Print Description

This is a vase mode print, so set your slicer accordingly!

Note that this was all designed for 0.4mm to 0.6mm extrusion width.  It might well work with larger nozzles and wider lines, but there's probably a point at which stacking will get a bit tight!

Print Dimensions

The larger Whirl Punnet occupies 89mm x 103mm on the print bed and is 60mm tall.

Supports Needed?

Not at all!  Designed for straightforward printing!

Scalability

As a vase mode print, the Whirl Punnet will scale readily up or down!

Print Orientation

Not surprisingly, this one prints right-way-up.

Further Thoughts

This is the point where it occurs to me that this could have a lid.  I should always make lids.  Someone always asks for a lid, and I always wonder why I didn't think of a lid earlier!  I'd better put it on the to-do list, which currently already has at least one other lid in waiting :D

What would a lid look like for this one, though?  An upside-down vase print that sits over the top?  Or perhaps an inset lid that takes advantage of the nesting?  And if the latter, how would a handle work?...

Happy printing!
