This awesome design was found on Printables from G33kt3ch studio@G33kt3chstudio but the hammer body and head (handle and sledge body) was in one solid piece over 103cm long so seemed unprintable. I split it up into sections based on the colors and used dowels to connect them together to make assembly as easy and solid as possible.

I have created a wall hanger for this and it is available in my other uploads.

Parts are organized by the three main colors - rust (brown or red), silver and yellow based on the super sledge in game. A wire/tube/hose with a diameter of 4mm will be needed to run from the pressure regulator, through the tube mount and into the hose connector at the base of the head but aside from a lot of glue that should be all that you need. I used irrigation tubing which cost about 50c.

This was a design created by another person and was incomplete and while I have made many adjustments to allow for greater tolerances you should be prepared to do sanding and test fitting before gluing any of these parts together. 

Please remember that this is a prop for display only and is not designed to be played with as a toy. If you plan on using this for cosplay I strongly recommend increasing the wall count and infill density considerably to make it strong enough for more rigorous applications.

Please like and rate this, your support is appreciated and I hope you enjoy this design!
