One way of making cheap wooden keycaps is using a laser cutter.
The fact you can't see such keycaps very often on r/mk may indicate their quality or sturdiness leave much to be desired.
However, according to the author, these work pretty well and it's relatively easy to do in a row (about 5 minutes per key).

He plans to use these in a macropad or as a media key so it's not too likely to be damaged with use.
Here is another similar project from more than a year ago by knot-a-robot with an open source vector file.
