In this episode of Bench Tested: A Ghostbusters Podcast, Charlie Harsh sits down with Grant from GSPropSmith to discuss the journey from modifying a Spirit Halloween proton pack to building a successful Ghostbusters prop shop.

Grant shares how joining the Oklahoma City Ghostbusters, buying his first 3D printer, and creating a custom belt gizmo eventually led to an Etsy business offering proton pack vent kits, magnetic leg hoses, handmade leather holsters, electronics, embroidered apparel, custom accessories, and complete proton pack commissions.

The conversation explores Grant’s focus on durability, affordability, customer service, and helping builders create gear that fits their own needs rather than chasing screen accuracy at any cost. They also discuss wireless smoke kits, handmade prop components, custom commissions, running a one-person Etsy shop, and the realities of balancing production, shipping, customer support, and everyday life.

Whether you are modifying your first Spirit Pack, upgrading a HasLab proton pack, planning a scratch build, or searching for reliable Ghostbusters prop accessories, this episode offers practical advice and an honest look behind the scenes of GSPropSmith.
