Universal Model Rocket Mounts (13mm - 29mm)

Summary This is a versatile set of printable motor mounts designed to help model rocket enthusiasts paint, display, and store their fleets. Designed to fit standard motor sizes (Estes, etc.), these mounts feature a clever geometry to ensure they fit even well-loved rockets with slightly bent motor tubes.The Problem & The SolutionBent Tubes? No Problem: Standard cylindrical plugs often get stuck if the cardboard motor tube is slightly crushed or bent. These mounts feature a 5-degree side cut (flat spot) along the cylinder, allowing them to slide easily into imperfect motor tubes while still providing a secure hold.Universal Handle: Each mount features a tapered bore (7.5mm to 8.5mm). This creates a tight pressure fit for either a 5/16" or 8mm wooden dowel.Sizes Included The files include mounts for the four most common motor diameters:Mini: 13mmStandard: 18mmLarge: 24mmExtra Large: 29mmUse CasesPainting Handle: Insert a dowel to hold the rocket while spray painting.
