I have not found a topic where users could share specific ideas to get feedback from the community in order to improve their design. I hope that this is the proper place to start such a topic. Just in case this is inappropriate, let me know and I will delete the post.
Challenge
For many products I want to design and print, I need large but thin plates (under 2 mm thick). They are much larger than the build plate of the Bambu lab printers. Think… limitless in size.
I was looking for a solution to create rigid 3-directional joints between such plates, without the use of glue. Below I will describe what I have done so far and I hope you can share your thoughts, solutions, comments or constructive criticisms.
Testing the Zipper Joint
Inspired by the zipper, I thought that such geometry would provide support in all three directions. The challenge was in selecting the optimal draft angle for the joint to maximize the constraints in all three directions without distorting the plates.
This is the model for the test protocol:
I imagine that many of you have already found other solutions for this challenge.
