Wanted Robin "Insert"

This is the insert for Robin. How it works? 1) Just print it lying down. Since i use textured plate i usually flip it so that facing part is good looking.2) Again i printed the STEP file as its good on the curved part. Also print the blank insert in white color filament as its good to diffuse the background light.3) Find my LED box model and print it. Then place this insert into any of the 9 slots and install the LED light and then you should be good to go.4) Although i make it with tight tolerance, this insert is removable and can be swap of mix with other insert.
