Check out your local maker/hacker space, library or community collage for access to a 3d printer locally. Check out 3Dhubs.com or makexyz.com for a directory listing of local 3d printing operators to get your parts printed for reasonable prices! Search from dozens of makers and see reviews and printed samples.

PLA Filament

These parts are optimized for printing in PLA material. The parts print best with custom supports around the tigger gaurd and around the small blade body barrel.

SemiFlex

The handle grip part will work and feel best printed in semiflex Ninjaflex TPE material.

Slicing Software

The recommend settings above should work with most slicing software. However, you are encouraged to use your own settings since 3D printers and slicing software will vary from printer to printer.

Support structures

Orient the model with the handle on the platform. This will give the top of the barrel a cleaner look.

You'll want to use custom supports for the GB-Handle.stl part.

Apply supports at a 60˚ with a resoultion of 4mm. The horizontal offset from part distance is set to .3mm.

Adjust supports

Use the cross section view to look inside of the barrel. Remove the supports inside of the cylinder holes to make removal easier.

Double check no extra support is left inside of the barrel cylinders.

Check simulation

Playback the simulation to insure the support structures will print as intended. 

Printing the tips

When printing small pointy objects, heat from the hot nozzle spreads throughout the object. This doesn’t allow layers to cool and the model ends up looking melted.

Print two models spaced on opposite sides of the bed. This will give the layers enough time to cool by moving the nozzle away from the spot and giving it plenty of time to cool. You can also print a small throw away cylinder if you don’t need two models.

Orientate blades with both flat sides facing each other - not like it's pictured above!

Support removal

Outer supports break away with ease. Supports holding the trigger gaurd required a little more force to remove. Use pliers to grip the middle of the structure and twist the supports off.

Carefully remove the supports around the small cylinder barrel.

Barrel support

Use a small spatula or Palette Knife to break away the support material inside the barrel. Carefully rotate the barrel so the knife can break off any material as you spin the barrel.

Filing trigger gaurd

Make sure the trigger gaurd is completely smoothed out and cleaned by using a hobby knife and then a file tool to remove any left over support material.
