Vase Mode Measuring Cup with scale on bottom

They don't include those measuring cups for washing powder anymore so, I made one to print out. This is a remix of my original design released earlier this week but now with a label to indicate the size.

Challenge

Getting the volume perfectly right. It clearly can be done so I had to do it.

Here's what's going on

Parameters of the OpenSCAD file are in bold.

The nice thing is: You decide on a bucket size in ml (milliliters). a bucket is one ring on the cup. So, if the bucket size is 25ml and the amount of buckets is 4 you get a cup with a total volume of 100ml and a ring every 25ml.

Then you choose a fitting diameter so it looks nice and the size of the chamfer but 1 is usually good in most cases.

Lastly the layer height of the number of bottom layers in and the thickness of the wall as well as the numbers layers

Wall thickness if required for Prusa Slicer because it only puts the perimeters completely inside the model. Use half the wall thickness if your slicer puts the perimeter exactly on the edge of the model. If your slicer is able to use vase mode to touch the model from the outside, set it to 0.

Why all this?

One could easily design a shape like this with a diameter and a height but the volume would be a number that looks like Pi which is not usable in most circumstances.
In this design, the volume of every bucket is defined as well as the diameter and the chamfer. The height is calculated precisely taking into account the reduction of the volume by the rings.

Mirror or not

If you want to have the inscription as a see through from above, uncheck mirror in the configurator. If you want to read it from below, turn mirror on.

Looks

Using a clear filament really shines in vase mode. Use some other color for the base.

Printing

Use vase mode and accept the settings it wants to apply. The print will not be waterproof unless specially treated.
