Nerf Automatic Pusher

thingiverse

Update 11-18-18 Major update: Lengthened slightly and added dwell for more stability. Fire control tabs added if you want to put in a Cherry submini switch for fire control. Old version is still available in Minimal_Pusher.zip. ===== This scotch yoke pusher design is designed to be a more stable variant for a printed autopusher. The minimal version is good for those builds where you want to put an auto-pusher in a Stryfe/Rayven/etc. Compared to a Rapidstrike pusher, this gets rid of two "unnecessary" small gears and relocates the motor. It also increases the gear ratio to 40:1, which enables the motor relocation but boosts fire rate by 50%. Recommended usage on 2S with either Fang Revamped for 13-14 dps or a torquey 3S motor for 9-10 dps. Required additional components: 1xx size hobby motor M2x5 motor mounting screw 4-40 nut (2) 4-40 screw - 3/8" or 1/2", any head (2) Rapidstrike worm gear or half of an Ajax Scientific worm gear (https://www.amazon.com/Ajax-Scientific-Plastic-0-82cm-Diameter/dp/B00EPQMKHQ/) 3/32" steel pin as axle. Alternate components can be substituted - a stiff piece of wire was used once during testing.
