3D Printed 18mm to 24mm Payload Nose Cone

Designed to allow flights of Jolly Logic altimeters in 18mm diameter airframes like the Viking, this 3D printed ABS nose cone fits in an 18mm body tube and attaches to the shock cord just like a typical nose cone.  But this nose cone flares out to 25mm, allowing room inside for a Jolly Logic altimeter or any other payload.  It includes 3 evenly distributed vent holes to allow outside air pressure to equalize inside the payload bay for accurate altimeter measurements.  You secure the nose cone cap to the base using 2 of the 6 included removable plastic rivets. We include extras in case you lose some of the small rivets. Add a small ball of paper towel or tissue to the forward end of the nose cone for padding to prevent rattle.
