These keycaps are based on some MOA keycaps I purchased.
I printed them at an angle on the base chamfer and manually added one dot of support at the end of the stem, using tree supports. This reduced waste compared to automatic supports, and printed just fine. It may be necessary to add a brim.
I borrowed the stem dimensions from the ScottoCaps.
The author remixed this model.
Borrowed the stem dimensions. Everything else is new.
