This is a highly-detailed intermodal 20ft tank. It is compatible with PIKO HO cars and my previous 20ft container (https://www.thingiverse.com/thing:3372971).
There are 2 versions of this model - one designed to be printed in one piece and multipart version. See instructions for more details.
** I have not yet printed this model! **
If you print it, please post photos and report issues.
Update 04/09/2019 I've made tank hollow so that it can be filled with metal parts to provide needed weight. I also added a small gap between tank and frame
