Nerf Automatic Pusher

thingiverse

Update 11-18-18 Major update: Lengthened slightly and added dwell for more stability, making it a more reliable choice. Fire control tabs have been added if you want to install a Cherry submini switch for fire control. The old version is still available in Minimal_Pusher.zip. This scotch yoke pusher design provides a stable variant for printed autopushers. It's ideal for those builds where you want to add an auto-pusher to a Stryfe, Rayven, or similar model. Compared to the Rapidstrike pusher, this design eliminates two small gears that were deemed unnecessary and relocates the motor. The gear ratio has been increased to 40:1, enabling motor relocation while boosting fire rate by 50%. Recommended usage on 2S with either Fang Revamped for a high performance of 13-14 dps or a torquey 3S motor for a reliable 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 * 3/32" steel pin as axle. Alternate components can be substituted, such as a stiff piece of wire that was used during testing.
