Step 0: create a 3d model
Step 1: 3d printing
Step 2: Preparing for painting.
Cut connectors, put them inside the box and cover with tape
Step 3: Primer/Painting
if your 3d model is red color, than it's better to use grey primer first to avoid too many layers of white painting)
Step 4: put LEDs strip inside
connect led strip
connect led strip to connectors
then I realised that with 5 pin connectors would be everything much easier and cleaner.
with 3/4 pin connector you need to be more careful when you connect one hexagon to another.
Step 5: checking if everything works
Step 6: making top part
It is easier to scoring and snapping plexiglass, but since i wanted to save some space and I used saw.
Step 7: setting all together
glue top to the main part / cut the fiber vinyl / apply it to the top
Step 8: Arduino & Blynk
Blynk QR code:
Arduino: To upload code you will need to add NodeMCU library to Arduino software
