This is a little 3D-printable sugar flatcar I made, based on both the HLW and LGB equivalents. This is designed to use Kadee 830 or 930 couplers, but I have made (And included) adaptors to give this LGB Hook & Loops. To assemble, put the wheels into the sides and slot the sides into the frame. (Glue may be needed) You can slot on either a low-side truck body or 6 posts. I've included some simple wheels with this, but you can also use LGB spoked wheels (Or equivalent).
