Design Process

The objective of this project was to design and manufacture a mobile workstation that consolidated multiple pieces of digital fabrication equipment into a compact, organized, and easily transportable unit for everyday classroom use. The cart was designed to accommodate two Bambu Lab P1S 3D printers, a Roland vinyl cutter, five readily accessible rolls of vinyl, and additional storage for commonly used materials while minimizing the amount of permanent workspace required.

The design was developed around manufacturing constraints from the outset. Every structural panel was designed in AutoCAD to fit within a standard 2' × 4' CNC router work envelope while maximizing material utilization from standard 2' × 4' plywood sheets. This approach simplified manufacturing, minimized waste, and ensured the design could be reproduced efficiently using readily available materials and equipment.

A complete digital assembly was created to verify component fit, equipment clearances, and structural alignment before manufacturing. Particular attention was given to overall rigidity by incorporating square structural geometry and mechanical fastening methods that would withstand years of continuous classroom use while remaining straightforward to assemble.

Fusion 360 was used to generate CNC toolpaths for machining each plywood component on a 3-axis CNC router. Following machining, the cart was assembled using standard wood screws along with hand and power tools. Caster wheels and an integrated handle were incorporated into the design to allow the workstation to be moved easily throughout the classroom while maintaining stability during operation.

Results

The completed cart has been in continuous daily classroom operation for more than two and a half years without requiring repairs or design modifications, demonstrating the durability and reliability of the design.

By consolidating multiple fabrication machines and their associated materials into a single mobile workstation, the cart significantly improves organization and frees valuable desk space within the classroom. The integrated vinyl storage allows operators to quickly change materials without replacing entire rolls, improving workflow efficiency during day-to-day operation.

This project demonstrates the application of mechanical design, design for manufacturing, CNC manufacturing, and design for assembly to develop a practical solution that has provided long-term value in an educational makerspace. By designing specifically around standard material sizes and CNC manufacturing constraints, the project also highlights the importance of considering manufacturability throughout the design process rather than as an afterthought.
