This is a support for balcony planters. It's made of PETG because of it's higher temperature resistance. It can hold a full planter and probably also a small car. I went a little crazy with the strength as I had no idea how much weight it was going to support. Turns out it's a lot less than I estimated. Heck, PLA may be more than enough for this print!

The design uses pins/dowels so that none of the parts are seeing any bending or moments, because printed plastics are known to creep (they deform/stretch over time). Since the parts only see tension or compression, it won't really matter if they do creep as you won't even notice.

The dowels are printed with 100% infill. The other parts have 15% honeycomb infill and 4 walls for extra resistance (I told you I went a bit crazy).

You'll need to print the following parts:

• 6 x dowel pins
• 2 x top supports
• 2 x guardrail supports
• 2 x L-shaped supports

The assembly is very simple, just look at the photos. I use a small amount of glue under the dowel pin heads (only) to make sure they stay put, except for the dowel pins nearest to the guard rail (no glue on these). I want to be able to open the top if needed.

BONUS: If by any chance you know how to use SolidWorks, feel free to rework the parts to your liking. The native SolidWorks 2020 files are included.
