These four parts will replace the laser-cut plywood parts on the Eggbot. All three major components are compatable with the wooden parts, so you could just change out the pen holder it would work fine. The plastic parts make the penholder much more stable. The penholder is designed to work with the Sharpie and Sharpie Micro. When changing pens, the alignment should be right on the spot.

In need of nutrition information for your large eggs? Then this drawing is just what you've been looking for!

This is a 3200 x 800 pixel plot intended for plotting with the Eggbot.

P.S. The text was rendered using the new Hershey Text extension by Windell Oskay and distributed with the latest Eggbot software release. It may be found in Inkscape under Extensions > Render > Hershey Text (after you update to the latest Eggbot software). The utility of that extension is not limited to just the Eggbot. Among other things, it provides nice, non-filled, single stroke fonts ideal for use in CNC and CNC-related applications.

Another geometric tiling for the Eggbot. This one somewhat reminiscent of Op Art. This drawing is in a 3200 by 800 pixel template.

Generating this and similar images is fairly simple. For example, this image was generated by drawing an isosceles triangle. Then it was "twisted" using the contributed "twist" extension under Extensions > Eggbot Contributed. The result of twisting was then cloned & tiled using Inkscape's Edit > Clone > Create Tiled Clones... tool.

I designed this a few months ago, but my machine couldn't print it until now. Sort of inspired by basalt column rock formations. Might look nice printed in Pencil Yellow

Making text for Unicorn or EggBot plots isn't always a fun process. Most tools require you to convert text into paths, and even then you get the outlines of shapes, which can often turn messy at small sizes.

mifga pointed me towards the Hershey fonts[1]. They're a set of fonts for vector plotters named after creator Dr. A. V. Hershey who made them for the National Bureau of Standards.

These files are in a weird, weird, format. But after some normalizing, wailing, and gnashing of teeth, I was able to write some code to parse them and spit them back out as SVG! Now you can use these fonts in your Unicorn drawings.

Each SVG contains a layout of one of the Hershey fonts. The hershey_svg.zip file below contains all of the SVG files. The hershey.zip file contains the (cleaned up) original .jhf files. math-drawing.svg is just an example of using these glyphs, including scaling and stretching. I think the result is nice!

To use these in Unicorn plots, you'll want to grab my Unicorn G-Code extension for Inkscape[2].

Step blocks are used in a variety of way in Milling machines. These light duty versions can be used to hold things to a CNC router table. I plan to make a variety of size or figure out how to make them Parametric.

These blocks are used in pairs to clamp or hold an item in place for machining. They come in assorted lengths and heights but all blocks are compatible with each other. The reason for making this thing is to have a version made out of a material that won't break your expensive end mills or drills when you cut into them by accident.

I rendered Matt's artwork on an egg using an Eggbot. This required resizing the original artwork in Inkscape. To make the egg drawing appear more similar to Matt's original, I further stretched the drawing horizontally with the amount of stretch given by the secant of the latitude. (I.e., it's stretched more and more as you approach the egg's poles.)

Mona Lisa rendered as TSP art in three "resolutions": 6910, 7933, and 12477 "cities" in the TSP tour. (TSP = Travelling Salesman Problem). The more cities, the more line segments. Eggbots will probably do best with the 6910 or 7933 versions.

(hint , specify a non-existent file name and it will make a default one of that name )

I took drepetto's AI file and cleaned it up a bit using Blends for the placement of the grooves. The Grooves in the file are stroked paths which will raster etch with the center cut. I also made little divots at the end of each line. Also, the numbers were created using my Helvetica Single Line file.
