Spiral Pencil Holder

Christmas is just around the corner an my dad suggested I design something for my granddad and print it for him. I thought it was a pretty cool idea so I made this so that he could have it on his desk. I have always been one for sharing the wealth, even when the code itself is not extremely complicated, so here you go! I hope you guys have fun with it. Be sure to tag this post if you print one yourself and feel free to leave what you think in the comments. Have a Merry Christmas!
