Rail-Fixing Hanging Hook

thingiverse

I needed some kind of hook to hang my upside-down planter from a tie-bar in the conservatory and this is the result. It clips nicely over a 16mm rod (the width lower 'slot' being a little smaller, so it snaps into place). There are then two small hooked ends over which I threaded some cord. I initially started parameterising the design, but ended up using a bunch of hard-coded magic numbers, so if you change any of the parameters, you'll probably need to change some of the other numbers to get the shape right. Instructions I printed this with a good thick shell and 20% infill, as I wanted it to be reasonably strong. Having said that, a previous version with a thinner shell and only 10% infill seems plenty strong enough.
