For this assignment we had to build a laptop stand made with parts cut out from a 15mm plywood board using a CNC router, which had to include at least one joint from a list by OpenDesk. We first had to make a cardboard prototype before drawing and assembling it digitally in Rhino 7. I chose to make a Blind Finger Tenon Joint, which was ideal to join wood pieces in right angles. I started by making the cardboard prototype. My idea was to have two long slanted pieces that joined in a 90 degree angle on one end and on the other end would have an upwards curve to stop the laptop from slipping. I showed it to my professor and we believed it would work, so I proceded to make it in Rhino. The design in Rhino was made by joining straight lines to make the "frame" and then six rectangles of equal size at one end to make the joint. Once the design was ready a mirrored copy was created. The rectangles and the main frame were joined, the common edges cut away and then the rectangles were trimmed in such a way that both pieces would fit together. Once they fit together in 2d, the designs were then extruded and made fit together the way they were designed to fit. Here are some pictures from the cardboard prototype and Rhino design.

Having the 3d design fit in Rhino, it was now the time to export the lines to Carbide Create and make a toolpath for the CNC router to cut the wood. The cutting process took around 7 minutes, and the post-processing took around an hour. For the post-processing I first cut the pieces off of the board with a saw and then sanded and filed the tabs so the faces were flat. I also sanded most of the loose fibres but couldn't get all of them. Then I applied wax to the wood and glued both pieces together, leaving them in a clamp until the start of the following class. Here are some pictures of the Carbide Create toolpath and the stand right after the cut was finished:

When I took the stand out of the machine and post-processed it, I realized the final stand was too big for my laptop, and while it could hold my computer, it didn't give me much confidence. Were I to do it again, I probably would consider using a different kind of joint so that the parts of the stand that held the computer were paralell instead of at an angle, and would make sure the computer is held near the middle instead of at the edges. Here are some pictures of the stand as it was being post-processed, glued and finally assembled with my computer on top of it.
