Wow Bro, I finally found your asparagus truck build. Every time I want to say something, it disappears off the list and I'm terrible at finding stuff here. I'm really surprised that a 3D print would be such a pain in the pooter. I can see breaking of tiny bits at that scale, but I can't understand the fender break and the terrible fit of the interior piece. He must use cheap resin to print his kits.
As for the interior fit Rick, I can only suggest breaking out the flex and grinding the hell out of it. I'm sure you'll whip this puppy into shape and I'll try to keep up from now on. I hope you hand a nice drive about and you enjoyed yourselves. Seriously though, people your age should be doing walk about's to keep in shape! Take care my friend...
Prost
Allen
