Minnesota Vikings Logo

thingiverse

Just a simple 4 layer logo for the Minnesota Vikings Football Team. You will have to draw this using an Ultrafine point maker. I believe the Sharpie brand pens have a .4mm pen tip. Your Eggbot/Sphere-O-Bot will also have to be very well tuned to make sure the 4 layers sign up. If there is any deviation in how far you seat the pen in the pen holder that will skew the alignment of the layers. As I found out with my recent multi-layer designs even keeping the pens the same exact distance from the sphere/egg isn't always enough as some of my pens were actually a little offset from the previous pens when they touch the Sphere. One tip I have for anyone trying to achieve better layer alignment is to take a sphere and select one marker that you will forever use as your "gold standard" and load the bot. Lower the pen so it leaves a single dot on the sphere. Then you can load another marker and do the same thing. If the two dots are perfectly aligned then when you use those two pens to draw different layers they will be perfectly aligned. If your pens do not align perfectly then you will have to find some other way to align them. If you are using the Sharpie Brand "Ultra Fine Tip" markers I'd suggest trying out my custom pen holder that friction fits the pen in the bot. You can then use small strips of clear packing tape to "shim" the pens so they are all aligned with your "gold standard" pen. https://www.thingiverse.com/thing:4201129
