High 5 Catapult

Unique Catapult HIGH-5! Fully adjustable. Throw Ping-Pong balls, foam golf balls, or even real golf balls, CAUTION: make sure you remove any breakables from the area. Print in place adjustable trigger, and Arm bearing to reduce assembly parts, may need a bit of breaking free after printing depending on your printer, quality. Printed with PLA material, 0.4mm nozzle and 0.15mm slices.

Once assembled make a few adjustments to get your hurling object to its target.  Adjust arm stop in 3 positions (A, B, C) from short travel stop to full travel stop.  Hand pivots using the 6 positions on the wrist. Insert your printed pins to lock in place.

Just add your favorite elastic device to provide the power you need. I just use a common rubber band.  Two holes in the Bearing Arm allow for different tensions or use both to double your power.
