Rethink Sharpie Top

thingiverse

I created this design specifically for my son BMD, since I had bought doodle tops from Amazon that were pricey, flimsy, and lacking in excitement. I ensured the Sharpie fits snugly by keeping it tight so it wouldn't come loose easily. Be prepared to apply a bit of force when inserting it into the 300-micron print for the first time. If you want to go with a 100-micron print instead, that might give a slightly better fit. The Sharpie spins wonderfully, as long as you've got a solid surface to spin it on. I recommend printing multiple versions and trying different colored Sharpies from the dollar store - it's an enjoyable activity for both kids and adults alike!
