Three finished 3D-printed Ghost Emoji figurines arranged on a grey countertop.

I made some Ghost Emoji, from rmoravcik’s design.

Printed on a Flashforge Adventurer 3 Lite in mostly white filament from Hatchbox. We used sparkle black PLA for the eyes, and the tongues in the FlashForge red sample that came with the printer.

I printed without supports, so the bottom of each ghost needed a bit of cleanup. I also found the tolerances for the eyes too tight, so I shrank them by 5% and those fit great.

I’ve sent some of these to the co-ghosts of GHOST PARTY 👻🎉!

Made a PyPortal Stand by Adafruit

I made a PyPortal Stand, printed from Adafruit's design.

This makes a great little desktop mini-display!

Printed on a FlashForge Finder in black PLA filament from Hatchbox.

It printed fine without supports or a raft. I printed with a brim, but the bottom still curled a bit because my print bed needs some adjustment. I evened it out with rubber feet, but that changed the center of mass a bit so it's a little forward-tippy. 🤷

It was easy to mount with nylon M2.5 standoffs and screws. I used a nut, small standoff, and medium screw for each of the 4 mounting holes, finger-tightened.

Description

Experimenting with laying out tweets on a sticky note. Thinking about some fun automated Unicorn plots.

Unfortunately, once again, I am not home to plot this. I will try to put up pictures later, but feel free to give this a shot in the meantime.

Feedback welcome!

Instructions

Using the Unicorn Inkscape extension: http://www.thingiverse.com/thing:5986

  1. Load tweet.svg in Inkscape
  2. Save as G-Code
  3. Plot

To Edit

  1. Edit the user_card, text, and timestamp layers. You’ll want to break up the groups.
  2. Use the Hershey Text extension for nice single-stroke text: http://www.evilmadscientist.com/article.php/hershey
  3. Plot.

To Change the Icon

  1. Grab your Twitter icon as a .JPG
  2. Import it into Inkscape.
  3. Select it and use the Path | Trace Bitmap option.

Description

To go with the new multiple-color plotting functionality of my Unicorn G-Code Output extension for Inkscape, here’s a new version of the Baltimore Node logo.

This one is ready to plot in 2 layers - all of the black parts at once, followed by all of the blue ones, with a pause at the beginning of each layer to allow a pen change.

I also made use of my Hershey Fonts in SVG to make the word “baltimore” more readable after plotting. This should make it look nice, for example, on an EggBot.

UPDATE!

I forgot to resize the original for a sticky note pad (whoops!) and I was right that the EggBot version needed layers beginning with a number.

Updated files attached and pictures added!

Instructions

If you have a Unicorn, try out the attached G-Code. It’s set to start with the pen centered over 0,0 and fits on a sticky note pad (75mm x 75mm).

If you have an EggBot, try plotting the SVG using the Layers dialog. Layer 1 is black, Layer 2 is blue.

Description

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].

[1] Hershey fonts - http://emergent.unpythonic.net/software/hershey
[2] Unicorn output for Inkscape - http://www.thingiverse.com/thing:5986

Instructions

To use these fonts in your Unicorn plots:

  1. Download the SVG file containing the font of your choice, or grab the whole hershey_svg.zip to get them all.
  2. In your Inkscape drawing, use File | Import to load the font you want
  3. Drag around and duplicate the characters that you want to use.
  4. Delete the ones that you don’t.
  5. Plot it!
    • (Unicorn users) Save your file and Save a Copy to get your .gcode!
    • (EggBot users) Plot directly from Inkscape. :)

Description

When I first heard of Graffiti Markup Language (GML)[1] I was like “An XML format for graffiti? Pfft!” Then yesterday I was like “Wait, I have a pen plotter.”

There are a ton of tags for you to play with at 000000book[2], so go get some files and start tagging … with post-it notes!

Thing-a-Day 2011 #2 - New features for inkscape-unicorn: pen registration and homing support

This post used to be on Posterous. I rescued my posts before Posterous shut down and am now sharing them here.

Today I made some improvements to the inkscape-unicorn plotter extension that I released yesterday.

Inkscape-unicorn-reg-and-homing

Specifically, I've added two things:

  • The option to do a pen-registration check at the beginning of each plot, taken from mifga's original.
  • The option to set where "home" is, for people who like to start their plots with the platform anywhere other than in the center.

This should help make some nice plots!

Description

One problem that has often plagued users of the MakerBot Unicorn[1] is the long and confusing chain of tools required to go from a nice vector drawing to a G-Code file that can be plotted from ReplicatorG.

mifga did an awesome tutorial[2] that made it possible to understand the steps needed to work all of these tools, but it was obvious that something better was needed.

So, I made a mashup of scribbles.py[3] and the Egg-Bot Driver for Inkscape[4] to bring you the inkscape-unicorn extension for Inkscape!

Once installed, this extension allows you to save files in “MakerBot Unicorn G-Code (*.gcode)” format!

Learn more, download, and contribute at the GitHub page for this project:

https://github.com/martymcguire/inkscape-unicorn

If you’re desperate, you can also download the zip file attached to this thing, but it is guaranteed to be out of date. Please get the latest version from GitHub. :)

Thanks to langfordw for the original Unicorn Logo[5] used as an example on this Thing.

UPDATES!

I’m updating and adding features to this script as my first days for the February Thing-A-Day. Updates below:

[1] Unicorn - http://store.makerbot.com/makerbot-unicorn-pen-plotter-kit.html
[2] mifga’s Unicorn Tutorial - http://wiki.makerbot.com/unicorn-tutorial-01
[3] scribbles.py - https://github.com/makerbot/Makerbot/tree/master/Unicorn/Scribbles%20Scripts
[4] Egg-Bot Driver for Inkscape - http://code.google.com/p/eggbotcode/
[5] Unicorn Logo by langfordw http://www.thingiverse.com/thing:4197

Instructions

From the README:

Install

Copy the contents of src/ to your Inkscape extensions/ folder.

Typical locations include:

  • OS X - /Applications/Inkscape.app/Contents/Resources/extensions
  • Linux - /usr/share/inkscape/extensions
  • Windows - C:\Program Files\Inkscape\share\extensions

Usage

  • Size and locate your image appropriately:
    • The CupCake CNC build platform size is 100mm x 100mm.
    • Setting units to mm in Inkscape makes it easy to size your drawing.
    • The extension will automatically attempt to center everything.
  • Convert all text to paths:
    • Select all text objects.
    • Choose Path | Object to Path.
  • Save as G-Code:
    • File | Save a Copy.
    • Select MakerBot Unicorn G-Code (*.gcode).
    • Save your file.
  • Preview
    • For OS X, Pleasant3D is great for this.
    • For other operating systems… I don’t know!
  • Print!
    • Open your .gcode file in ReplicatorG
    • Set up your Unicorn and pen.
    • Center your build platform.
    • Click the Build button!
