This item is the same as my previous barrel except it has a removed area that can be used to weight the barrel down. I used rocks and epoxy to get a higher density than the plastic at 100%. No support should be required for the weighted cutout area.
Printed in ABS with 3 shell layers, 7 top and bottom layers. This was printed at 100% infill and layer height 0.12mm, feel free to change them to your desired amounts.
