Folding fan for holographic build plate

Designed to maximize build plate exposure for transfer of holographic patterns, but you could switch colors, add text or images, or lots of other customizations. 
Blades lock into each other via t-shaped pins to open and close like a normal paper fan.

Print one of each: FirstBlade, LastBlade, PivotPinTop, and PivotPinBottom
Print five of each: BladeA and Blade B 
To assemble, put FirstBlade onto PivotPinBottom, then insert pin of FirstBlade into slot of BladeA at a 90-degree angle, then rotate the blade hole down to and on PivotPinBottom as shown in video.
Put a BladeB on next and alternate between A & B until you run out, then finish with LastBlade. 
Once all blades are on the PivotPinTop should press fit into PivotPinBottom to hold it all together.

Print with 0.2mm layer heights until you get to the top of the pin where it flares out and smaller layers are better.
If you want a color swap, in the middle of the four 0.2mm layers of each blade is the best place to do it.
I would avoid using silk filaments for the pins due to the much poorer layer adhesion- I would be afraid they would snap off if printed in silk. I used black tough PLA for bottom layers and pin tops with a few layers of sparkling purple on the top blade faces. PET-G would probably also work, but watch out for globs on the pins.
I used a 0.6mm nozzle, since that's mostly what's on my printer and it worked fine in prototyping, but when I printed an entire fan only ~80% of the pins worked due to the lower resolution. A 0.4mm nozzle would probably work but I don't have one to test it out with. I switched to my 0.25mm nozzle and a 0.1mm layer height for the pins and got reliable printing. 

You can print this entire fan in two beds on the XL or other larger printer.
If using a holographic build plate I recommend using 15mm/s first layer speed.
