This is a cap designed to fit over the XT60 connector. I usually keep all my Lipo batteries together in a box and it has always been in the back of my head that one fateful day two batteries will short themselves together. Hence, a simple cap.I've also attached a pattern of 2 and pattern of 6 for those who want to print multiple parts.Printed on the Replicator with the following settings Firmware 5.5 Replicatorg 0037Raft/Support: None infill: 85% Number of Shells: 1 layer Height: .2mm feedrate: 60 mm/s traverse rate: 100 mm/s extruder temp: 230CPrint Time was approximately 17-20 Min.
