We bought our 3D printer to make a magnetically activated oil door latch for our Vans RV-7, and then started thinking about the other parts that could be made. The spark plug wire guard shown below came next. Other parts are going through the design phase now.
Opening a store to give other builders who have yet to acquire a 3D printer a source of low cost parts seemed logical. Then, Dolly started adding her Yarn Craft items.
