Also, you may have mentioned this before, but what mounts do you use?
I kind of eluded to what it was but didn't call them out. But they are basically acrylic shelves that I had been using for a long time in my display cabinets. They are cheap (can get a pack of 6, different sizes, on Amazon for $20), you can easily drill them, score and snap them and heat them up to bend them a bit into a new shape.
I am going to try the 'heat and bending' method on my TIE Advanced.
On the model side, I have settled on these for the inserts pictured below. I find a bit of epoxy and sometimes stir sticks (for re-enforcement) is more than enough to hold the model up.
I use the brass one on the left for the actual model and the one on the right if I am installing it into a wooden base. I like this size as I can get either the metal rod pictured below or the different-sized bolts pictured and it all comes from my local hardware store which is nice in a pinch. This is also the same size thread pattern as the "camera" mounts I see a lot of people use. I think the size is "1/4-20".
Then I just epoxy the insert into the kit:
I have moved away from complicated/fancy bases to something that I feel is pretty minimalistic and does not detract too much from the build. I also bought a pack of neodymium magnets that I want to experiment with for some different mounting options.
