I needed a way to mount a Trinket and power jack, so I designed and printed one.
When working with 3D printers, you start with an object file. The object is a solid chunk of 3D geometry. To get that out to the printer, it needs to be “sliced” into layers. This is similar to a laser printer. There, you start with a PDF or PostScript that defines a circle here and … Continue reading Octocat MRI
After the initial failure described in yesterday’s blog post about the RatRacer, I thought I would scale down the problem a bit. I figured it would be easier to iterate through design tweaks when big parts took 20 minutes to print versus 120 minutes per part. If I ended up with a sound design for … Continue reading Son of RatRacer: Mouse Car
As you might have guessed from the previous post about attic rats, I had a few leftover rat traps. And what does one do with leftover traps? I supposed you could do something cool with ping pong balls, but I did not have nearly enough traps or ping pong balls. I have a vague childhood … Continue reading On designing and building the Rat Racer
On using a 3D printer to deal with rats…
This is the final part in a series of three, describing the hardware behind the puzzle gadget I designed for Curtis’ birthday puzzle game.
Part 2 in a series. The story so far: a secret surprise puzzle game, a gadget that had to “contain” a piece of paper upon opening, the decision to make that gadget electronic with screen and keypad and to make that paper printed on demand by a thermal printer. Would it work???
Recently, I had the pleasure of building a puzzle-hunt gadget. The circumstances surrounding this particular device and hunt were extremely unique. The puzzle hunt was for an audience of one — a surprise birthday party for my friend Curtis.
About a year ago I designed and printed a 1/4 cup measuring cup. You see, I needed a good way to measure cat food. I only needed the one size, so buying a whole set of measuring cups seemed like a waste. With a MakerBot in the other room, I figured it was best to make just the one size of measuring cup.
Inspired by the book “Gödel, Escher, Bach,” I designed a 3D-printable monogram cube that you can customize with your own initials.
