M5 Bolt-Drawn Wire Mesh Post Tensioner
A post-mounted mesh tensioner, printed in place: a 110 x 48 x 18 mm C-channel frame that you screw to a fence or coop post with four #10 (4.8 mm) wood screws. Inside it a captive slider rides on the post face. Tie the mesh edge to the slider's two 4.5 mm tie-wire holes, then turn an M5 hex bolt that goes through the 5.5 mm end-wall hole into an M5 nut in the slider's 8.3 mm slot. That draws sagging chicken wire or hardware cloth tight over about 30 mm of travel.
