VERY nice work sensei. It is exactly what I was referring to - the proper joint type and fit. I don't see much adhesive under tension there
I understand that yours are your designs but unfortunately, there are many kits out there that don't necessarily have as much thought put into the joint types.

I "Dabbled" in a business for a few years where about 50% of the business was the manufacture of various resin compounds including Adhesives ranging from PVA's through Acrylates to Epoxies and Urethanes
