A 3d model of the rocket hammer / jet hammer used by Doctor Ido in the movie Alita Battle Angelthe model is a total of 168cm tall with the hammer part being 82cm long but the model can easily be scaled and remain printablethe entire model is designed for good printability and practicality and includes both parametric files for easy editing and printable stl and mesh files with high meshing qualityit also includes the full one part model as well as one split up into 14 parts that can be fit into a regular printer and assembled using 6 1600mm long and 4 620mm long 6mm diameter support rods although those would have to be resized if the model is scaled and the parts can be further divided up for even easier printingthe rear / jet part of the hammer has an opening which can fit a fan and LED's which combined with fabric can be used to make an LED jet effectI will probably add some modified/updated variants when the bluray of the movie releases - those will be added to this page for free and I will try to keep part boundaris for the assembly the same so that the parts that don't actually change stay the same and can be used on

Print and photos by Gregory Belland - I designed it full scale but he scaled it down and with a resin printer and painting skills managed to get some amazing detail into this size
