Barbershop Cup and Stacking Slot Cups! (Patreon)

Howdy, wonderful people!

I do love things that stack.  So, I made some cups, though the shorter one looks more like a tray than a cup, and there's a taller one that's more like a caddy than a cup.  Anyway, suffice to say, roughly-cylindrical-shaped thingies that stack nicely on each other.  Those are the Stacking Slot Cups.

While that was fun, I couldn't help veering off on tangents, as I tend to do, and started exploring ways that I could get some colour into the slots.  The obvious initial step was to just have the slots run all the way through and pop an insert in behind, but that got me thinking about whether the coloured insert could some how protrude beyond the outside of the exterior cup... and this is where it ended up!

You might notice that both the interior and exterior slant inwards at the top.  That's because they, too are stackable.  In fact, the exteriors will stack just fine without the inners, and those inners are strictly optional.

Excitingly (okay, not that excitingly) the Stacking Slot Cups will stack neatly with the Barbershop Cups, because the profiles for the stacking interfaces are exactly the same, so you can mix them up if you really want to!  This also means that the lid will fit either one just fine :)

Print Description

These are regular-style prints, designed for straightforward printing!  However, bear in mind that if you're printing the inner parts for the Barbershop Cup that you'll want to be conscious of overextrusion or other dimensional irregularities that might stop the inner fitting neatly inside the outer.  The gap is fairly generous, but it doesn't take much to get in the way!

Print Dimensions

The Stacking Slot Cups are 80mm x 80mm on the print bed and range from 39mm to 118mm tall.

The Barbershop Cup exterior occupies 92mm x 92mm on the print bed.  The short version is 64mm tall and the tall version is 109mm

Supports needed?

No supports required!

Infill?

Infill shouldn't make too much difference to any of these, though it wouldn't hurt to either increase infill or perimeter count for the Barbershop Cup exterior, so that the twisty parts are nice and strong.

Scalability

The Stacking Slot Cups will scale without any issues at all! (though, they might get tricky to stack if you go very small, and the lid will behave similarly)

The Barbershop Cup will scale just fine if you're not using the interior insert.  If you are using the inserts, then you might need to play with perimeter adjustments in your slicer to keep things fitting nicely.

Print Orientation

Everything prints right-way up, including the inserts!

Further Thoughts

I did contemplate a version of this for a multimaterial setup!  However, that would really be completely unnecessary when it's already designed to be printed and assembled.  Much as I love multimaterial prints, they do add time and failure risk, so there needs to be a compelling reason to actually go that way!

Happy printing!
