Anything A-Frame Sign

I had a problem, this was my solution. Design considerations were flat folding, durability and strength for repeated usage long term.

Free-standing A-frame sign.  Will happily stand open on its own but I added bracing arms to ensure it won't collapse outside on a breezy day or from a knock.

Laterally asymmetric hinges that lock into each other - just print a side twice and they fit together and hinge smoothly around Maker's Supply M3 shoulder screws.

Bracing arms mount with M3 screws. Button heads are a nice low profile and anything from 12 to 16mm will be fine. I use washers on the fixed side screws.

You can customise your text/design on the sign faces a number of ways. My example here is a secondary CAD model assembled in the right order to print correctly (note the single extrusion line sprues connecting the backs of all the letters into one model for simple colouring).

You could import the blank STEP file into CAD and etch a design 0.01mm into the surface and re-import for painting in Bambu  Studio.

You could import SVGs or add text directly in Bambu Studio with the text tool.  Heck, you could print it blank and go nuts with sharpies!

Print profile consists of 4 plates

• Plate 1 is an example of using a second embedded model to generate text.
• Plate 2 is a blank side of the sign ready for your customisation
• Plate 3 is a skeletonised rear panel for those that don't need a double sided sign
• Plate 4 is a spare set of bracing arms. Every plate has a set, disable/delete as you need.

You could print this in about any plastic you want. Since mine lives in the car and gets exposed to Australian summer heat & UV, I chose PETG as the most robust of easy-to-print plastics.
