I haven't printed this yet, but it is held together with 1" wooden dowels and stands at about 4 feet long. this should fit on an ender 3 sized printer or similar. A 265mm build height is required unless you want to cut it more. Assembly should be straightforward, use the picture of the full hammer to see the orientation of the handle pieces and where the middle ring should go. The 1" dowel may need to be sanded down for parts to fit.
