T-Post Corner Insulator

thingiverse

I was needing a corner insulator for a T-Post electric fence for my garden. All I could find were egg shaped insulators for the inside corners of a fence. I really wanted one that I could string fencing continuously around the outside and have full coverage for small critters like rabbits. I designed this insulator in Solidworks to fit between the nubs on a 1.25lb/ft T-Post with a locking pin to lock it into place in-between the nubs. Just slide it over the post and slide the pin in place and it gives a 360 degree insulator for wire or poly rope. This is still a work in progress. It might need to be scaled slightly for other posts. I am providing the design files as parasolid files so they can be imported into most any version of Solidworks or other CAD programs as well as the STL files of the last build. Print Settings Printer Brand: SeeMeCNC Printer: Rostock MAX Rafts: No Supports: No Resolution: 0.45mm Nozzle 0.25mm layers Infill: 25% Notes: I am currently printing it with 4 shell layers and 25% honeycomb infill using PLA. I will probably switch over to one of the PET or ABS materials I have for UV resistance and outdoor use. I am using a 0.45mm nozzle in a E3D extruder. The printer is a SeeMeCNC Rostock Max Gen 1. I have tried it with and without support and it prints much better without any support. I use a 5mm brim and have been using diluted glue stick in a thin film on a heated glass plate for adhesion. This has also worked well with the PET and Nylon materials as well. I am using the Repetier software and slicer for my parts. Post-Printing Some cleanup of the pin slot on the insulator may be needed as well as cleaning up the edges and faces of the pin. I've tried to leave adequate margins for an easy pin fit and as long as the post is installed with the nubs facing outward the pin should be held in place by the wire or rope.
