Who you gonna call?

I grew up during the first wave of Ghostbusters movies and loved the franchise ever since. I had all the toys as a kid. Back then it was a lot harder to make your own custom toys. My first few weeks with my own 3D printer has been the usual stage of ‘print everything I can’ — trying to get as many things off of my long Thingiverse ‘Like’ list as I can.

Personally, I liked the university. They gave us money and facilities, we didn’t have to produce anything! You’ve never been out of college! You don’t know what it’s like out there! I’ve *worked* in the private sector. They expect *results*. — Ray Stanz (Ghostbusters 1984)

The week the new Ghostbusters movie came out in July, I printed out a version of the new Ecto-1 hood ornament in nGen silver metallic filament. It made a great hood ornament for the truck as we went to go see the movie at the drive-in.

 

This week with some red and white filament in hand I printed out the classic Ghostbusters logo — one for my maker workbench at home and one for my office at work. It’s not bad enough to print 1 of everything, lately I seem to be printing lots of stuff in duplicate.

“[as a ghost leaves on the subway] I guess he’s going to Queens – he’s going to be the third scariest thing on that train.” — Patty Tolan (Ghostbusters 2016)

If you want to print either of these models for yourself I posted my settings and tips up on Thingiverse here (for Ecto-1 Hood ornament) and here (for Ghostbusters Logo)

Take care,

After creating my own model and printing it the next challenge I wanted to try out was printing in to colors of filament. I don’t have a flexy dual extruder yet (though I do want one) I wanted to take a shot at designing something that would work well being printed with two colors at different layers, meaning I could pause the print, swap filaments, purge and then resume the print.

I was inspired by some of the stickers and images I’ve seen online for Reverse Engineers and decided to make a fun little sign for my maker bench.

Model Details:
I designed this model in SketchUp and exported it as an *.stl file. It can easily scaled to a larger size. I wanted to minimize the amount of warping and among of filament used. If you want a thicker base just scale up in the Z axis.

Print Details: 
Printed on LulzBot Taz 6
Dark Gray and Orange nGen Filament
20% infill, Standard Resolution and Speed
Printed scaled 2.0 in X and Y axes, and at 3.0 in the Z axis.  This gives me something a little bigger than a business card.

The trick was sitting there watching the print and pausing at just the right time to swap the filament. This meant finding the first layer wherein the background is complete and we are about to start printing the text which is proud of that surface. I looked at the layer view in Cura and could figure out when I wanted to do that filament swap. Worked great on the first print.  At some point I want to look at hacking the GCode or similar means to automate the pause, but I wanted to do it as fast as possible so the print didn’t cool down too much as I didn’t want any unnecessary adhesion issues.

I’m very happy with how this print came out and look forward to trying this technique with other models.

This model is a great addition to any maker workbench. You can download the model from Thingiverse here: http://www.thingiverse.com/thing:1693100

If you make one, please leave a comment or link to your make photo.

Take care,
