thingiverse

This 3D object is a transition from Este BT-50 to BT-65 tubing. The distance between the two sizes of tubes (transition taper length) is 2.0 inches (50.8mm). It is similar to the Estes TA-5065 (P/N 70020) transition/adapter. There are eight models: 1) Solid, 2) Solid with a 3.2mm hole to allow for screw eyes to be fastened to it, 3) Hollow, 4) Hollow with end caps. 5-8) End caps fit the ends of the Hollow2 transition. One has no hole and the other has a 1/8 inch (3.2mm) hole for the attachment of eyebolts. Several rocket kits that use BT-65 tubing are: Estes Scramber (kit# 1237) Estes Olympus (kit# 7293) Estes Green Eggs (kit# 7301) Other transitions / adapters: BT-5 to BT-20 Transition https://www.thingiverse.com/thing:4921365 BT-5 to BT-50 Transition https://www.thingiverse.com/thing:4927099 BT-20 to BT-50 Transition https://www.thingiverse.com/thing:4892191 BT-20 to BT-55 Transition https://www.thingiverse.com/thing:4931950 BT-20 to BT-60 Transition / Adapter https://www.thingiverse.com/thing:4949461 Estes BT-50 to BT-55 Tube Adapter / Transition https://www.thingiverse.com/thing:4744003 BT-50 to BT-60 Transition https://www.thingiverse.com/thing:4894927 BT-55 to BT-60 Transition / Adapter https://www.thingiverse.com/thing:4962698
