Darn Socks / Zehensocken Stopfer

I needed something to darn my favorite toe socks from japan, so I quickly designed something in Fusion 360, and I want to share this with you. 

I printed it with 

no botom layer 

and 4 walls 

and 0 infill

at 0.2 layer height. 

print it as in the pictures (you need to turn it, I am still learning fusion 360 and need to figure out why my model is on its side)
