If you ever find the need to make your own 3D picture frames using my 2D pieces, you can use this file: frames template (right click and download .sxd file). There are instructions on how to use this file type in my laser cutting notes.
Overall, it was a bit of a challenge to find a proper fit for the cardboard. I started out by using a tab fit for my design but quickly found that it required much more precision. Hence, I ended up using a sliding fit. The sliding fit also differed greatly depending on the type of the cardboard being used. For example, the lighter cardboard could not be held together easily using the same cut sizes. I had to make sure that I used the proper type of cardboard since there is some pressure in my picture frame project
Some random notes on this specific project:
- Use a 0.1" wide cut for a sliding fit in the harder cardboard. - Use a 0.12" wide cut for parts that need to be less sturdy but fit together nicely. - If you plan on using a long piece of cardboard to stand on end, don't use longer than 8" if its only 1" wide. The cardboard is just not strong enough. - Try to avoid the folds and such in the cardboard box foldout, it does have an impact on the final structure.
