DEFAULT DIMENSIONS ARE RATHER WEAK ON THE RING

But this can be very easily fixed, thanks to it being…

FULLY PARAMETRIC!

As is standard for me, files designed from scratch in Fusion360 are 100% parametric, meaning every single dimension is easily changeable in a single menu, and the design will update accordingly. I normally use GRK 114069 self-tapping cabinet screws, so the included files are sized approximately for two of those holding a rather light conical vase of fake flowers 50mm in diameter. I do not know if the current size for the holder ring is strong enough for heavier things. I wouldn't tempt fate on it, especially since I've found PLA (and sometimes PETG!) will flex into a “muscle” memory under sustained tension and sag over time, but it will hold a lighter thing of that size without flexing one bit.

An adjusted size could probably hold a short-handled sledgehammer without flexing too much, though I would absolutely use supporting triangular fins if your aim is to support more weight. I didn't include an example like this both because I never printed this part off to get a feel for it, and as well the clearance of the part you're holding to the triangular support fins varies wildly based on what you put there. I didn't see much of a point in trying to put in extra effort where I'll never use it, but the Fusion360 file is there should someone else decide to do so (please remix this if you decide to do this so others can benefit from it!)

Obviously, ADJUST DIMENSIONS AS NEEDED!!! (which is super easy too!)

Worth noting!

This can be flipped over so the mounting tab is underneath instead of on top. Probably obvious to 95% of you, but for the other 5% :) Though 99% of you probably won't realize that due to the holes being horizontally aligned, this will NOT work for fully securing it into a stud. One or both screws will have to screw into drywall unless you get a spot where you get two studs side-by-side (like just below the corners of a window). You might need drywall anchors, though the GRK screws I use do pretty great when they're only “snug” into the wall, and that only applies if you're screwing it into drywall and not something like a shelf. Do be mindful of that however.

Purpose

I originally made this to mount our wedding flower vases to the wall. They're in a conical vase, and they were pretty secure being held at the point where the vase is 50mm wide. Given they are lightweight, I prioritized the outer ring to be fairly thin. We wound up wedging the flowers between the shelves and the adjacent wall instead, so these mounts were no longer needed. This WILL print and work perfectly fine for lighter uses as it uses the same F360 parameters as my other designs that have served me extremely well (including a yet-to-be-released project too!). I actually made it a bit thicker than I normally do due to the distance away from the wall, so it might hold up to heavier use, but do pay attention to both immediate failures on the smaller ring as well as it sagging over time
