Press Fit Tree Jewelry Holder

I wanted to make a press fit design that was interesting but also functional so I can use it everyday. I have been needing a jewelry holder which is what influenced my design and the reading influenced my design as well.This reading shifted the way I think about assembly in my design process. Traditionally, I approached projects in a top-down way. Sketching ideas, measuring in Fusion, and forcing materials to fit my plan. But the chapter emphasized that “materials are passive and they listen to our commands” only in a conventional sense. In reality, assembly can emerge from the bottom up. I was struck by the examples of stigmergy and robotic swarms, where complex systems arise without centralized control. This made me reconsider how I design press-fit joints or modular pieces. Rather than dictating every outcome, I can allow materials and tolerances to guide assembly. I also connected with the idea that “by losing control, we can gain surprising new results”. For me, this means embracing unexpected outcomes in laser-cut forms, such as joints fitting more loosely or tightly than planned and as opportunities for new functions rather than flaws.

1. Fusion
2. 1/8th inch plywood
3. Laser Cutter

I began by sketching my idea, which was a press-fit tree made from three different shapes. The base consisted of four cut-out slots where the press-fit joints would hold the structure upright. The other two pieces represented tree trunks with branching forms, designed to slide into each other through an opening in the middle. I intentionally shaped the branches to function as holders for rings and jewelry, giving the piece both form and utility.

I modeled the base in Fusion with precise measurements to ensure stability. Accuracy here was crucial so that the tree trunks could slot securely into the stand.

Next, I designed the two trunk pieces, carefully aligning dimensions so they would slide together perfectly at the center. I also ensured that the press-fit joints at the bottom of the trunks matched the base openings for a snug fit.

I reviewed the design, checked that it matched the 1/8-inch plywood material thickness, and factored in adjustments for the laser cutter’s kerf (0.25 mm). These refinements ensured the joints would lock tightly without being too loose or too tight.

After exporting the file to Adobe Illustrator, I laser cut the design. One issue occurred when a line was missing on one of the branches, so the cut didn’t go all the way through. I resolved this by finishing the cut with an X-Acto knife.

Finally, I pressed the pieces into place: the trunks sliding together at the center and then fitting securely into the base. The finished design successfully held its form and served its purpose as both a structural press-fit project and a functional jewelry holder.
