Bulkhead spacer. Identical to that found in our sled mounting kits. Designed to act as a spacer for sled attachement to an existing bulkhead eyebolt without needing to remove the existing lock nut. This allows your sled to be removed while keeping the recovery attachment point in place on the bulkhead.
Printed from a professional grade PETG plastic with a high Tg (Glass transition) of 76 deg C (169 deg F), so it will hold up to the most extreme flying site conditions. All parts are solid (100% infill), so no internal voids or honeycombs.
