About
The studio
Prime Tower Designs is led by Mike Brunswick, who spent 20 years in technical program management at Microsoft. When his 3D designs found a following on MakerWorld, he turned to design full time, founding The Brunswick Workshop LLC with his wife Elizabeth.
The studio focuses on optical mechanisms and kinetic objects: engineering principles turned into things you can hold. Mike's work has been honored in multiple 3D printing design contests, including a first-place finish in Bambu Lab's global Magic Trick contest, and he hosted MakerWorld's "Old World Magic" contest, which drew over 600 entries.
