So it would seem that finding a pattern for Mando and Grogu snowflakes has led me down a rabbit hole of trying to find other nerdy snowflakes to make. Luckily there are plenty of instructables online so I’m now able to share with you my findings!
Legend of Zelda & Mario

The Nifty Nerd has posted their own Legend of Zelda and Mario snowflakes. These ones look a little more complicated than the Mando and Grogu one but it is completely doable. I highly recommend using a coated laserjet paper though if you don’t want it to rip as easily seeing as there are so many cuts in them.
Super Heroes

LEGO

Who doesn’t love LEGO? From the popular LEGO movies to the games odds are someone in your house loves them. These paper snowflakes are a cool craft for not just kids but also adults. They say that if you have a single hole punch too it will help with the eyes. Check them out at pinkstripeysocks.com.
Harry Potter

Any “Harry Potter” fans in the house? Well I’ve found some cool Harry Potter snowflakes that you can make yourself! The ones by designsbymissmandee are a bit more complicated. But any of these can be printed out and cut with an exact-o knife if you have one.
