Spindle Sander Guard

At Protocase during Fall 2020, I designed safety guards to aid the tab removal process that follows CNC and lathe operations on sheet metal parts.

The design required different guard configurations for each spindle sander size, with an adjustable arm using slotted holes to accommodate various part geometries. This flexibility was critical for the guards to be practical across the shop's range of work.

This was my first time using 3D printers to prototype a design before committing to production. The iterative prototyping process — print, test, refine — taught me the value of rapid iteration and significantly improved the final design.
