Summary

Not easy to print. Maximum layer height 0.1mm for the SMD socket.

Lid is optional
Version D is slightly easier to print as it is slightly thicker behind the SMD

There are different SMD5050, socket fitting via size 100% - 110% (Ultra Bright White SMD 110%). At 110% it is best to pull a shrink tube over your legs so that they are back on tension.

Ultra Bright SMD 5050 to 12 Volt only with load resistance 2W (from 70 Ohm otherwise too hot) My SMD are dimmable via a potentiometer
