Sometimes my hobbies cross over into each other. This year I attended WordCamp US in Nashville and had an idea. Why not download and make a bow tie with a WordPress logo on it?
First I went to Thingiverse and I quickly found this one. I already had the WordPress logo from converting the SVG with Fusion 360 and I began to work on combining the two files.
About an hour later I swore profusely. I had a lot of problems. My PC was a little under powered. Fusion 360 can do amazing things and you can design a V8 engine with it including all the parts. My limited Fusion 360 skills were failing me.
All I wanted to do was take the logo, position it on the tie and export the results to a new STL file for printing. But I'm not really good at manipulating imported objects that way in a tool like that.
Tinkercad to the Rescue!
Autodesk makes Fusion 360 but they also have a 3D editor that lives on the web and runs in your browser called Tinkercad. I imported the two files, positioned the logo where I wanted it and exported it for printing.
It took me all of 5 minutes. The first pass had the logo a little too thin and it broke too easily. It was also upside down; I thought the clip on bow tie would work that way. Sometimes I make poor choices.
Just as before with my WordPress coin, I wanted the bow tie to be one color and the logo to be another. My working printer does this like so:
- Print using one color filament till the 59th layer. I used a tool to figure that out.
- Move the nozzle to the corner and the print away from the nozzle. The nozzle is 200° C and that will melt any plastic it is near.
- Beep loudly. This is an important step as the 3D printer is in the basement.
- I remove the old filament and insert the new color.
- Log into Octopi via my iPhone's browser and tell the printer to resume.
That's it. The bow tie came out well and I printed a few more. Did I mention that I sometimes go overboard? I printed 9.
Opensource All of The Things
The bow tie I downloaded is licensed via Creative Commons – Attribution and Thingiverse provides an easy to print attribution card HTML. Which I could not incorporate into this post except as a graphic and a link.
The 3D printer community is mostly opensource and these were printed on a Prusa i3 clone. I used Simplify 3D to slice the file into gcode but there are some really good opensource slicers such as Cura and Slic3r. I've had some bad luck with Slic3r but I think I sorted that out now.
