This is a short how-to guide for creating your own brim on a 3D model in CAD to prevent a model from coming loose from the print bed. This can come in handy in case your slicer software does not include a correct brim suitable for your part.
When 3D printing taller objects which are relatively narrow, the printed object can possibly come loose from the bed, resulting in a failed print. The higher the object becomes, the larger the risk, due to to increasing mechanical advantage for larger height to width ratios.
