Lab 2

For this lab, I practiced modeling objects from real life, an object for laser cutting, and wood joints in Rhino.

For part A, I modeled a table scraper. I drew out the dimensions of the scraper in my sketchbook, then took pictures of the table scraper from its profile, front, and top view.

I used these pictures to model the scraper as accurately as I could in Rhino. I think it turned out more accurately than I was expecting.

For part B, I modeled a phone stand in Rhino and sent my model to the Slicer program to create jigsaw pieces out of cardboard.

The goal of using Slicer was to be able to assemble the phone stand entirely out of cardboard. I sliced the main face up horizontally in order to imitate a kind of "wall" that a device can rest against (instead of a "fence" that would be the result from vertical slicing). I used glue to fully assemble this model, as it came in two pieces. The final piece differs from my original model in that I did not include the phone stand's wings, since some people around me have told me that they do not contribute to the functionality of the design.

For part C, I modeled two objects that may live in the surroundings of my phone stand, which in this case were a smartphone and a coffee mug. The idea behind this was that since someone may use a phone stand to hold their phone in place, they may be busy doing another task or just relaxing while watching something on the screen, and therefore there may be warm coffee involved. The smartphone is there because the phone stand would be lonely without a phone to hold.

Finally, for part D, I modeled some wood joints to test out on the laser cutter. I modeled three types of joints in total: the halving with elliptical tenon joint, the lapped dovetail, and the secret finger tenons. Since these all of these joints required two layers to complete, I used 1/8-inch plywood to construct the secondary layers while using 1/4-inch plywood to construct the primary layers.

An issue that arose while gluing the layers together on the lapped dovetail joint was that the secondary layers got slightly mismatched with the primary layers, which caused the joinery pieces to not align with each other perfectly. Overall though, I think it was a success.
