As part of my ongoing seach to have more things for my empty rail carts I decided to make these concrete slabs. at the moment they just fit losely in the cart without anything holding them back from sliding all over the place.

3D PRINTING SETTINGS:
printed in PLA at 210C
60mm/s
0.2mm layer hight

sanding will probbebly be required to make the slabs have sharp 90 degree corners
