Thermal Conductivity Meter

Construction

Documentation

Most of the manufacturing in this project is done an a 3D printer. This has been incredibly convenient for building complex shapes and furthering construction progress without having to be present while the printer is working. Once all printing has been done, the remaining construction will involve assembly and soldering.

One significant advancement that has been made in the manufacturing process was the tuning of the AnyCubuc Kobra 2 Neo printer to use PETG filament. This was previously thought to be a difficult and time-consuming task, but ended up being nearly effortless. Using PETG allows all printed components to have much more strength and longevity than they would’ve had PLA been used, without all the hassle of using ABS filament on Hogue’s more finicky printers.

Parts IBB-20-002 & IBB-20-006 post-printing. These parts took about 23 hours at 50% infill to produce on this AnyCubic Kobra 2 Neo using Elegoo PETG filament.
Test fitting IBB-20-002. The previous iteration (seen on the left) had screw holes that were too spaced out for screws to thread into the double nuts. The old iteration had the center of the vertically-aligned holes spaced an inch apart, while the new iteration has the outermost edges of the holes spaced an inch apart.
