Embedded Files
In this project, I designed and built a laser-cut laptop stand with press-fit components.
Supplies
Fusion 360
1/4" Plywood
Laser Cutter
Step 1: Concept Sketch
Most laptop stands are one-dimensional and have no other uses, so I wanted to create something that is multi-use, and doesn't look like a laptop stand when not in use. The goal with the curves was to make it look like a cylinder that had been deformed.
Step 2: CAD Sketch
To design all the legs, I created a single sketch for all seven. Most dimensions are function-based, so I can change parameters like material thickness, and the model will universally change to account for the new material.
Step 3: CAD Assembly
I pieced together the model in an assembly to confirm that my design would be assemblable once laser cut.
Step 4: Tuning for Press-fit
To account for the kerf of the laser cutter, I created a test block with pegs and holes of varying designed overlaps. Laser-cut pieces will have a different dimension than the design file due to the burned-off material. This means pegs should be laser-cut larger designed for, and holes smaller. A 0.15mm overlap between the peg and hole had my desired friction fit.
Step 5: Laser-cut Layout
All the components in the assembly were converted to DXF files and I merged them into one Illustrator file for laser cutting.
Step 6: Laser Cutting
The file was sent to the laser cutter which cut the 1/4" plywood.
