This is a remix of the awesome Door Opener Advance and DO Advance - Upgrade parts that allows the use of touch screens with some basic hardware from around the house and Amazon!

What was changed:

1. Added a touch screen tip holder to the blade.
2. Added a inner channel for a wire (coat hanger) to the blade, to allow capacitive touch through the opener bolt.
3. Made both the blade and inlay higher to support to support the touch screen tip holder.
4. Reworked the top bolt tolerances due to the change in inner height
5. Added a spring channel to hold spring and make assembly easier.

What you will now need:

1. 2x M5X16
2. 4x M3X16
3. 1x M3X8
4. A 25.5mm X 4.5mm spring: bascially any spring from an old pen will work I got mine from: Amazon
5. A approx 76mm length of 2.4-2.5mm wire, I used some old wire hangers I had, just make sure to strip off the protective coating and trim off any sharp ends
6. A nice tip for a stylus pen, I like the mesh ones, and found these: Amazon they seem to have a M5 thread on them so it makes tapping them using a bolt very easy

Basically you print out the parts and assemble them the same way as the author of the Door Opener Advance shows, you will add the cap and push the wire down the tube (see instructions) so that it touches the cap, and then screw in the opening bolt. To use it you simply unfold the opener and then touch the metal bolt (keeping your hand away from the screens) and you can now use this on someone's dirty tablet, or the ATM. I am planning on getting some capacitive filament in the mail and some long m3 bolts so I will add some more models once I have tested those.

Hopefully you find this useful and give a shout out to the original author who graciously let me remix this! Please make these give them out, share them, remix it, and lets keep our hands away from those surfaces!
