Success! I applied a +0.1 offset to the plate lettering, and a -0.1 offset to the insert lettering. I also made the bar holding the letters together slightly smaller than the recess on the plate into which it fits. The result is a snug fit, but it works. Thanks for all the suggestions. I haven’t ruled out the “pause at height and change the filament suggestions, but it was fun solving this with your collective help.

<p>I want to create two piece labels for storage containers. The main piece would be the “badge” which would have text cut out of it (e.g. “Paint”, “Electrical” etc.). The second piece would be a positive of the text which is would be in a different colour, and would fit inside the cut out on the badge. Because of the tolerance of 3D printers, I need to make the insert slightly smaller than the cut out. Initially, I thought I could just scale the insert but that would affect the letter spacing. Then I thought it would work if I could somehow taper the letters so they are slightly smaller at the top than the bottom. So my question is, how I do that. I did the original in OpenScad but I would try Fusion360 if that’s a better solution. Any and all suggestions are welcome. Thanks.</p>

Why dealing with inserts while you can print the letters on top of the plate by changing filament at height! There are various questions on changing filament here.

If creating a number of items, it would be simpler to print all the “plates” and then print all the inserts. And I also prefer the look where the letters are not higher than the backing plate.

@RonVentura: While I agree, if the plates are not terribly large you could print a number together at the same time, and then one filament-change operation would serve all of the batch.

can you use a flat colored sheet instead of positive text? it would show through the "stencil" of the negative letters. that way the text can be colored without sizing reqs...

In OpenSCAD, apply the `offset` transformation to inset the letter outlines before extruding them. However you may find it works better to fill the sunken letter shapes with nail polish then remove the overflow with acetone; see my question & answer <https://3dprinting.stackexchange.com/a/10872/11157>.

Fusion 360 can be easily used to **alter the design**. It has a button under `Construction > Edit > Push/Pull` [![enter image description here](https://i.sstatic.net/51SAC.png)](https://i.sstatic.net/51SAC.png). Using this tool allows to select one or more surfaces and shift them all outside or inside as needed.

An alternative would be to include the **size difference in design**. By selecting a line or loop and then pressing `O` opens a menu that easily creates an outline shifted by a specified ammount.

**Tapering** the extrusion is also easy: When extruding, one can choose to extrude with a -1°, resulting in a smaller size on the far side from the extrusion. positive angles make the far side larger.
