Without steppin on any toes or throwing a wrench in the monkey works. I recently completed a Panzer III build and had replaced said bin because the stock Taigen or Heng Long and available Mato bins are of the wrong size and detail.
SOL makes the bin. I got it from rctanks.de awhile ago. Wasn't a fun process. The Taigen turret bin was metal so, yeah not fun.
