Because 3D Printing…

3D Lock

Sometimes you see amusing things at the space. Take for instance, this lock on the bathroom stall. The black piece is actually 3D printed. Yes, someone took the time to measure, and model, and 3D print a rectangular bar to fix the bathroom stall door lock.

Never mind that a piece of wood, or plastic, or metal could have probably done the job in much less time, sometimes you just need to 3D print a replacement part for a bathroom stall door and you bust out the 3D printer and in a matter of hours you’ve got the part you need!

3D Printed Telescope Spider

I am designing and building a homemade telescope, loosely following designs from here. While a lot of their components are ingeniously designed, I wasn’t satisfied with the spider plans they provided. I decided to try my hand at designing my own spider in Fusion 360 (using their free enthusiast subscription) and 3D printing it.

The spider snugly fits in an 8″ diameter tube. There are 3 slots in the perimeter to allow rotational alignment along the axis of the tube. There are 3 additional screws in the central cylinder that tilt the diagonal mirror holder and provided height adjustment. The diagonal holder has multiple grooves to provide more surface area for the silicone to bond to. The surface the mirror mounts on is on a 45. The entire thing was printed in PLA on Mark’s SOM printer (huge thanks to Mark for helping out).

A similar design could be constructed in the machine shop with multiple operations and perhaps even some welding, but the ease of designing this in Fusion 360 along with the little setup involved in the 3D printing process made this an ideal path to choose.

Time To Get Nerdy!

Nerdy Head

Make sure not to miss this weekend’s Nerdy Derby at American Science and Surplus. Adrian and the rest of the nerdy team will be helping kids and kids at heart turn blocks of wood into rolling masterpieces of speed. If you have not been to a Nerdy Derby event this will be one not to miss.  3D printed wheels have been coming in from printers all over the city and from our Makerspace 80 at a time.

Building a car is easy and there will be a nice long track to race down once you’ve finished your creation.  You start by picking a block of wood and some wheels. After a bit of nailing its off to nerdy up your car from piles of amazing decorations. Makers are encouraged to decorate, test, and re-decorate. Everything that you glue onto a car affects the way it moves down the track. See you there!
