Khung Mũ Biểu Diễn Ánh Sáng Pixel

This is a two piece frame to connect 4 flexible panels. i.e. you will need to print this two times.

The panels themselves need to be taped together to form a circle (or tube).  This frame is then inserted to keep it rigid, it can then be placed around the hat of your choice.

Cable tie the pieces together to keep everything in place.

Cutouts are supplied for cable ties to tie together and to support a raspberry pi zero 2w to control the lights

What you'll also need -
4x 32x8 flexible panels e.g. https://buildalightshow.com/pixels/169-32x8-flex-panel-5v.html
Raspberry Pi 0 2w
5v battery pack

I used the “Lights on Thunder Road” tutorial on building and wiring the hat.  This gives a good basis.  The frame here is used instead of stuffing as described in the video.,

 Both 3 3mf and the Fusion 360 f3d files are included so you can easily make modifications.

I used PETG to print on a Prusa Mk3.

This print is a VERY tight fit on the baseplate, so you may need to turn off the skirt to make it fit.
