Electric fence wire support

thingiverse

Raccoons were digging holes in the lawn while searching for tasty worms and insects. The support is designed to accept a 1mm solid wire that snaps into place with a twist at the top feature. I used aluminum wire from a welding spool as the electric fence wire. The support was printed in black ABS for some protection against UV light. It was printed hollow because it has enough strength for the task and prints faster. To get strong ABS prints, you will need a heated bed and an enclosure with heat. The original electric pet fence had very visible and strong wire supports that were also ugly. This support is much less visible and not as strong, which meets my needs perfectly. I designed this in Fusion 360 and printed it on a Cetus mk2 extended printer with a 110C heated Ultrabase build surface (plus many other printer mods). Tip: In an emergency, place a paper bag over the top of the printer to capture hot air from the heated bed and reduce cold drafts on the print surface. With a 3-inch gap between the bag and the heated surface, the internal air temperature reached 50C. Tip: Almost all original Cetus parts were printed in PLA, but PLA softens above 50C, which is a problem in a heated chamber. I reprinted them in ABS specifically the Y-Axis Endstop Holder, downloading the printable STL zip file bundle from Cetus/Tiertime. -Peter
