Want to use the Makerbot thermal barrier, heated barrel,and nozzle on a RepRap 2.0 pinchwheel extruder but don't know how you are going to keep the thermal barrier from slipping out of the extruder base without using a large washer and long cap screws to hold it all in place? Use this fancy retainer part. It is shelled out and totally encases the thermal barrier preventing it from moving, and bulging. I printed mine from Polycarb on an FDM Titan. See the pics. This is in addition to gluing in the PTFE. Mechanical attachment along with glue.
