The Printer Project.
A purpose-built stabiliser clip designed to prevent stand bags twisting and shifting on MGI electric golf trolleys. What started as a mechanical CAD fix for a frustrating on-course problem evolved into a fully validated micro-business feasibility study.
The Problem
MGI electric trolleys are designed for cart bags, not stand bags. Golfers who use stand bags on MGI trolleys experience the bag twisting, rocking, and slipping during use. MGI's own accessory range does not address this issue. Furthermore, MGI holds approximately 90% of Australia's electric golf trolley market, meaning this is a widespread and unmet need.
Iterative Design & Manufacture
The MGI Bag Fastener is a pair of 3D-printed polymer clips that attach to the frame of an MGI electric golf trolley. The clips secure a stand bag firmly against the trolley frame, eliminating rotation and lateral movement during transport, particularly across uneven terrain.
For outdoor durability and structural integrity, the primary material used is PLA+ or UV-resistant PETG. Utilizing a Bambu Lab printer, the print time per set is optimized to 2.45 hours, keeping the material cost per set under $2.00 AUD.
