A couple of weeks ago I decided to buy a 3d Printer Kit from Prusa Research and put it together. You can read more about that on www.nanohawk.com where I focus on electronics. One of the great uses for a 3d printer is printing hard to find parts. These plastic/rubber sockets are a perfect application.
I’m using a $600 printer, $18/lb plastic and free software to model them. I’m currently printing version 19 trying to get the dimensions just right. In the photos above I show version 13 in PLA a starch based biodegradeable plastic. I want the final part to be in ABS, and didn’t realize it shrinks a few percent when printed. 🙁 So now I’m working on adjusting that out. It takes about 45 minutes and costs around 15 cents to print one.
I have more than a few parts that are hard to get or out of production on this bus.
Here are some photos of the lead up to the photo above:
An ABS version being printed
The assembled printer
A drawing from Autodesk Fusion 360, which is free for hobbyist and startup use.
A rendering from the same program
versions 1 through 12…. they don’t always turn out so great…..
A rendering from Simplify 3d which is the software that transforms the drawing into “g-code” that the printer understands.
Another rendering. There is a torus or donut shaped ring visible. I moved it further down to retain the ball.
Another picture of the 3d printer, fully assembled.
