==============================================
Made this for my splicer costume for PAX East 2017!
..and emblazoned with Ryan Industries right on the handle!

UPDATE: The newest revision is posted here for your benefit. It includes all the new features from lessons I learned while sanding, painting, and assembling:

• mating features for glue-up alignment
• coarse-fit threads for easy adjustment
• better knurling on the nut
• correctly mirrored text (oops!)
  Originally modeled after an image of a RIGID-brand monkey wrench - the body of which is 14" long! And no, splicers don't actually use wrenches.. until now :-)

Printing
Layers thicker than 0.2mm are a sanding nightmare. Don't do it. On my printer, total print time can be less than 21 hours and all parts fit on the bed. Avoid printing with support - I learned this the hard way, as removal of strongly adhered support material in the wrench's neck is super awkward and cosmetically unnecessary.

Assembly
Notice the diagram (photo #2) - the components have mating features for easy alignment when gluing!

• lightly sand every surface which will be glued (I use 100-grit sandpaper)
• 2 holes are included in the wrench handle for 1/4" dowels (I used steel, but wood or plastic should work)

Painting
Sand everything, then spray. Prime it dark! Like black. I did the main body with red and some "rust"-colored highlights. Masking tape is your friend.

Leveling:
Maximize your print quality by leveling first! I use my 3 square print:

Go forth and make! :-D
