If you have some broken clips that secure your wooden dado to the wall but cannot find anywhere that sells them, then this might be what you're looking for.

they are a nice snug fit unlike the loose fit of the original part.

I believe dado was made by Richard Burbidge.

I printed with .8mm shell 100% infil .2mm layer height

Depending on your print bed a small brim may help it stick.
