I recently received my Intrepid 8x10 and am very much enjoying it! But like some, I ran into a few issues. I managed to crack one of the lower tabs that help hold the ground glass to the camera. This happened when I was trying to have the magnets break free so I could rotate the ground glass orientation. Upon inspection, I noticed that the tabs, at least of my camera, were printed in a less than ideal orientation for strength.
So I designed alternatives. They are similar to the originals though I added a fillet towards the top to help with the hinge action of the ground glass breaking free of the magnets.
These are meant to be printed on their side such that the layers are in the direction of force resulting in a stronger part. Attached to the camera that means the lines are vertical.
I recommend printing these in PETG fully solid with 6 perimeters.
For those that are not able to print these, I do offer printed versions on my photography store (see bitbybitphoto.com).
