My First 3D Printed Object

I have been excited about the potential for 3D printing for quite some time.

Shortly after our local library acquired a couple 3D printers, I took the mandatory course, where we were taught the two primary rules of printing at the library:

Rule #1) Don’t touch the heating element
Rule #2) Don’t print guns

Course completed, I started to think about applications.  What can’t you just buy, what makes sense to print?

The idea of combining Duplo and Brio seemed like a great idea – I was thinking of an elaborate track with bridges over bridges, and Duplo seemed almost perfect for the job.  What I really wanted was a piece with a wooden train (Brio) top, and Duplo bottom.

A quick search revealed that I wasn’t the first person to think about this, someone had already designed a Duplo/Brio bridge support system.  Looking into this further, and loading these parts into 3D printing software revealed that each segment would take about 2 hours to print – the maximum time allowed on the library’s printer.  Given that a simple bridge would require at least four segments, I looked for alternate ideas and stumbled across the Duplo/Brio wagon.

I downloaded the file, went to the library, and printed it out.  83 minutes later, my train was completed.  I attached the wheels to the body with paper clips, and glued fridge magnets to the ends for the couplings.  I was quite pleased with the end product (see photo).  The library charged just under $5 for the printing time, which is about what a train car costs from a local toy store.

Taking this idea further, I thought I may try to design my own toy 3D printed TTC subway or street car for wooden train tracks.  I have  occasionally seen them available commercially, but they are generally hard to come by.
