Designed for the HackFab Evolution Tandem Axle Pulling Sled. This 3D printed Weight Tray Insert is meant to fit snugly in the weight box of the pulling sled and provide a clean and organized way to fit weights into the sled. It was designed around the very common LYMAN lead weight ingots that can be found on ebay (we do not sell them). Each tier holds 12 ingots, face down. The ingots vary in weight but are approximately 1lb ea. These are designed to be stackable in the box, however there is a version difference between the bottom tier and secondary tiers. The bottom layer has cutouts for the button head screws in the bottom of the box, and has a base for the center weight that can be inserted upright. The secondary tiers are flat on the bottom and have a passthru hole for the center weight. For maximum weight placement (37 ingots), you would need 1 bottom tier, and 2 secondary tiers. Includes:1x 3d printed weight tray Dimensions:Approx 7.7" square
