I modeled this in tinker cad off of the dimensions of the original one. I didn't have any black abs at the time so I just used green. The one that came with the bag was a piece of junk. It was hollow and broke within a month.
I used 100% infill but you could most likely do a 50% with 6 or so perimeters. I used an anycubic ulrabase on my anet a8 for this print. I also have an enclosure around my printer for printing in ABS.
