I only used two sided tape on my projects in the beginning, but soon realized that it was called a spoilboard for a reason. I know use corner jigs cut from outdoor plywood with a small curve in the center to hold old my projects. I also use self drilling screws to easily lock the jigs in place.
On large projects I use a first cut of 1mm to outline all my projects so that I know where to safely put the self drilling screws.
The jigs are double functions as it was designed to also help me in clamping pieces square. I have added the project file below.
Here is a link to a sample screw box. Buy them in quantity since they have a very large head, I can also use them force the project piece onto the spoilboard nice and flat.

For the clamps, notice there is an outside piece and an inside piece.

could you convert the attachment to a standard .crv? vs 3D

From my experiences, people tend to run their machines too SLOW, not too fast.

It's almost as if there's a contest of who can take the longest time to do a relief cut. "here it is, after 36 hours cutting" type stuff.

I had a few moments so I manually redrew these. Maximum size of cutter that can cut these is 3/8" (9mm).
