Is it hard to play those classic arcade titles that used "triggersticks", "top-fire sticks" or "flight sticks", When all you have is a standard bat-top? Well, the fix is in!
This design lets you make an adapter that snaps on to any HAPP-style bat-top arcade stick, and adds a clicky trigger to it, and, optionally, a standard normally open pushbutton for your thumb on top. When not in use, it can be removed so your control panel stays clutter-free!

and as always, read the instructions page for help with printing and assembly. Game On!

You will need a few things to get this together:
*Some wire (a few colors are helpful, something flexible)
*a Microswitch (I used Radio Shack part # 275-0016)
*a momentary push button switch (I used part #275-0644 -Optional)
*Solder and soldering iron.
*An old bicycle inner tube (to cut a 1-inch band from)
*Hot glue gun
*a Velcro cable tie strap
*Drill bits and a drill
Print the two "Trigstick" parts (Front and Topback stl files)
you will need to print a trigger button, I supplied two, one with a flat face, the other with a curved face. take your pick (I used the flat one)
insert the trigger into the hole in the front half of the stick from the inside; the lip on the long edge of the trigger should face the top of the opening.
solder two wires to your microswitch, and wire it in the "normally open" configuration (A ground wire to the "C" terminal, and your signal wire to the "NO" terminal)
using hot glue, adhere your switch to the little shelf, behind the button; I removed the lever from my microswitch, so the trigger presses the little "nub" of the switch; this gives a good response, and tucks the switch into the front shell nicely.
Optionally, you can drill a hole on the "Top/Back" portion of the stick, and wire up the push-button switch and mount it there. There is a recessed area on that part on the inside, to help you locate placement. It is configured for right-handed use; Mirroring this part will allow for left-handed use. You may need to trim or file part of the front half to clear your button when assembled. wire up your switch, and connect your ground leads from the two, as you will only need a single, common ground connection.
Take your inner tube, and cut a one inch band from it (about 25.4mm) you basically want a fat rubber band. put the front and top/back sections together and put this inner tube band around them to hold the shells together, and give it some give for easy
installation and removal.
Lastly, hot glue an end of the velcro strap to the inside-bottom edge of the front shell, this is to secure the adapter in place, loom the wire harness, and ensure it does not pop off the stick in use.
you can optionally sleeve the wires as I have. be creative in hooking up to your arcade board, the buttons should wire up like any
arcade button.
To use, just pop the adapter on to your joystick first by pushing it onto the ball from the top, then by twisting it forward, onto the stick, wrap and secure the velcro around the base of the stick and your harness, and you're in business.
Feel free to modify this to your liking. If you can make a better version, I would like to see it (heck, I may adopt it!)
This is a rough guide; I made this part to accept different push buttons, there are even two screw holes on the front shell, if you want to do a permanent install. use removable connectors so it can be plugged in, etc.
I have included "Mock-up_stick.stl" for reference purposes if you are confused.
