At my kids school they don’t celebrate Halloween, but they have a yearly crazy hair (or hat) day. And of course I can’t simply get some purple hair spay and be done with it. Not even close.
Last year I made a Mr Krupp hat from Captain underpants for my daughter:
A small incandescent light bulb makes the light, the windows will be laser cut out of some sort of transparent plastic. The small groove is for inserting some hand rails laser cut from heavy paper.
Everything else will be laser printed in white PLA, then painted with acrylic paint. The whole thing is only 15 cm tall, which makes many of the features a bit small.
I decided to try the Form 1 at the space for the little housing at the top, since it has some quite small features. But the Form1 still had the expired resin in it, so the end result was not great:
I need a boost converter to take the 3V from the two AAA batteries up to 5V for the Arduino Micro and the light bulb. The one I had lying around was a little too small, so I removed the USB connector and cut off the unused part of the PCB:
I also printed the battery holder which doubles as lightbulb socket and the platform on top of the tower. And I ended up laser cutting the hand rail from card stock. It’s so tiny!
