Print in clear resin
When printed, cure and wash good!
Fill arrow with desired color resin, and cure again.
Use a syringe with dull needle, start at arrow tip hole, and let it vent throu the other holes.
When filled, clean the insides of the keycap.
If desired you can paint the inside with nailpolish/resin to make “background” color.
Apply a layer of clear resin all over upper sides, and cure again, for polish finnish.
