FDL-1 ergonomic handle and trigger

I printed one of the excellently designed FDL-1 robotic foam dart launchers. (http://www.thingiverse.com/thing:1651854)

Unfortunately the handle didn't fit my smaller hands well. This is a more ergonomic handle taken from a real life gun and modified to be a little more foam darty while preserving as much of the original FDL-1 look and functionality as possible.

I'm using a 1050mAh battery I was able to aquire locally. I'll know soon if the hit to run time is an issue.

You'll need:

  • 2 m2.5 bolts to hold the microswitch to the handle,
  • 1 6-32 socket head cap screw, to screw into the top of the trigger. It pushes the lever of the microswitch.
  • 3 countersunk style 6-32 bolts to hold the handle to the handle plate
  • a tiny microswitch to fit the slot in the plate. You may need to file the plate slightly to get the lever of the microswitch to clear it.
  • the same 6-32 tap you used to clear the holes on the FDL-1

Print settings are identical to the FDL-1 except that I have not oriented the parts for best printing.

  • The handle also requires support, print it inverted with the flange side down.
  • Print the piece that attaches the guard to the main body the same as the original (the guard slot has only been widened slightly)
  • The guard has been widened slightly to fully cover the slot in the bottom of the handle. It should be printed on it's side
    -The trigger should be printed with it's top side down.
  • The base has a thin wall near the microswitch hole. Break it off after printing. Run your microswitch wire up the channel and under the tabs. Print it tab-side down (rounded edges up)

Note: this is the handle only. See the original blaster for the rest.

Edit: The unedited OnShape document is on the original FDL-1 page, and this is a link to my version with myhandle modifications. Thanks Jessie for letting me convert that for public use!
