<p>Weight weenies rejoice! Here's an M5x0.8 screw with a T10 (Torx) head designed to fill unused holes on a bicycle frame for water bottle cages and similar. More secure than press-in plugs, and lighter than most of them when printed for minimal weight.</p><p>Torque spec is - <i>there isn't one</i>. Tighten it by hand with a ¼" driver bit - <i>not</i> in a handle or driver - and stop turning once it snugs up. It's not going to rattle out. If you over tighten, it will break.</p><p>With a 0.4mm nozzle you can print this at 0.1 mm with two shells, 3 top and bottom layers and zero infill for an average weight of 0.15g each! That checks <i>any</i> weight weenie box and looks better than electrical tape over the holes.&nbsp;</p><p>Many thanks to Mike Shields on the <a href="https://www.cyclingtips.com/">CyclingTips</a> <a href="https://cyclingtips.com/signup/">VeloClub</a> Slack for calling out all the ways this design could be improved!</p>
