29mm fin can for Estes BT-56 body tube.

thingiverse

This is a compatible replacement fin set for the Estes Eliminator rocket, which can also work effectively for other projects. The fins mount seamlessly on an existing BT-56, and with some careful sanding or adjustment, they'll fit perfectly on a BT-55 as well. This fin can provides exceptional stability across all mid-power 29mm motors. A photo of the fins attached to the unfinished rocket is included, but it needs to be viewed in "large view" mode for clear visibility - otherwise, it's just a faded purple tube. Print Settings: Rafts: None Supports: None Resolution: 0.2mm Infill: 100% Notes: To achieve the best results, set the print settings to single shell only. Using two shells has caused internal separation of fins for unknown reasons - and in some cases, PLA can warp when heated, which can be alleviated by carefully sanding out the interior and coating with epoxy. My final prints will utilize ABS, and future upgrades will focus on improving performance at supersonic speeds.
