Simple and quick print (32min for 12 pieces with a 0.4mm nozzle) to hold WS2812B strips or any other LED strip with 10mm x 0.4mm size. The slot has a depth of 0.5mm, so please take care of elephant foots.
I printend them in PETG Jet Black and glued them with a drop of hot glue onto my screen backside.
Added also the STEP files if someone whats to modify them.
The author remixed this model.
