CNC Ergon Slingshot DXF / Zwille / Steinschleuder
- Part A
- Part B
- Part C = Part A + Part C
I have converted the 3D model of the ergonomic Slingshot for CNC. You can mill two sides and then glue them together with wood glue. I rounded off the edges at the end with a router. A Slingshot can also be used very well as a template to create a copy manually with the scroll saw.
Made on CNC3018PRO
- MDF Laminate 5.6 mm (two sides glued together)
- Fxy 400 mm / minute (ideal feed for MDF)
- Fz 100 mm / minute
- milling cutter 1.58 mm (2.08 mm at CAM software)
To correct the spindle frictions, I add 0.5 mm to the real diameter of 1.58 mm. This means that for CNC3018PRO in the CAM software the diameter is given as 2.08 mm for a 1.58 mm cutter.
The material is very sturdy and feels comfortable in the hand. The outside of the laminate is protected with a layer of varnish. I painted the edges several times with wood glaze.
Pocket slingshot version
This slingshot don't fits very well in the pocket. I have created another CNC ergononic pocket slingshot (thing-5993766) model for only three fingers. You can also create a second slingshot with the same anchor point.

hunting shoots:
- bird (head) 15 Joule (11 FPE)
- squirrel (head) 15 Joule (11 FPE)
- rabbit (head) 15 Joule (11 FPE)
- fox (rib) 50 Joule (35 FPE)
- deer (rib) 200 Joule (150 FPE)
- hog (rib) 270 Joule (200 FPE)
The survey shows that for hunting would need very strong rubber bands and heavy ammunition. In many countries hunting with a slingshot is not allowed.
