Graduated Cylinder Hanger Rack 3D Print Files (free)

[F4U]

Since i use a lot of Rodinal and do cyanotype, these processes call for measuring small amounts of chemistry that only small graduated cylinders can deal with. Being a cheapskate i opted for this Ebay set of 3 cylinders But how do you store them? If you just put them on your shelf or bench sitting on their base, it's only a matter of time before you knock one over, most likely breaking it. Further, storing them upright has shown that even 1 drop of water in them never dries. so I designed this rack that stores them upside down. It is 6 different stl files that you can print on a small printer like an Ender 3, and glue the parts together with E6000 glue. I made the base so that you can fill it up with gravel or pennies, or whatever and then glue on the bottom cover. That way the rack will be so bottom-heavy that knocking it over is unlikely. This is is the info on the cylinders I bought, and what the rack looks like. If anybody responds to this post wanting the stl files, I'll post them.

Neat. You could remove probably around 70% of the material from that design to make it print faster, without any loss in function. I've it a try. With 3D printing I find you have to rethink the construction. Were used to thinking in terms of "a beam here, a small board there", but we aren't limited to such building blocks. A more function approach is more optimal, and then leave out any material that's not needed.

Yeah, I tend to over-engineer things, but I have a Neptune 4 Max, which prints a lot faster than my Ender 3. But it is what it is. The foremost thing I had in mind was being bottom heavy. Those glass cylinders are something you don't want tipping over. Plus, at 10% infill it really didn't use up very much filament. I just finished mine lat night and haven't gone to the bank to get a few rolls of pennies for the base, and there's no sand or small gravel around here.

Nice idea. I find the tubes with the little collar in the middle pretty idiot proof if you knock them over.
