Pistol Grip Saw

Summary:

Four piece ergonomic handle to securely and safely hold reciprocating (Sawzall) blades. Uses three M4x16 machine screws and nuts. 

Hardware Note:

Before printing be sure to select the correct “Left Handle” for your hardware. One is a counter sink (C-Sink) for a flat head machine screw. The other handle is a counterbore (C-Bore) for pan head and hex socket machine screws.

Print Settings:

PLA, Smooth Plate, 0.4 Nozzle, 0.2 Layer Height, Arachne Walls, 4 Wall Loops, 4 Top Shell, 4 Bottom Shell, 20% Grid Infill, No Supports needed. Feel free to pause when printing the handle to change the color in the contouring.
 

Directions for Assembly:

After printing use the inner sleves to mark the center of the hole you need to drill in the recip saw blade. I used a sharpie, then a punch to create a divot. Use a 3/16" (4.5-5mm) drill bit to enlarge the hole that is already in the blade and create a new hole aligned with the hole on the inter blade holder. 

The drill bit should be titanium coated HHS, cobalt, or carbide because the blades are made from hardened steel. Drilling hardened steel should also be done at a low RPM and feedrate, lubricant is also highly recommended. Be sure to file off any burrs created by drilling.

Once drilled, sandwich the blade between the two inner sleeves and ensure the holes are aligned. Use three M4x16 machine screws and nuts to sandwich all pieces together

Happy printing and happy sawing! Please upload a make and rate the model and print profile.

Different Style Saw Handle:

There is a link to a different style recip saw blade handle I created that uses the same hole pattern if you are drilling holes in blades:
