If you've lost or otherwise need a backup to the original puller for your precision pinball flipper, then this 3d printed version will do the trick. 

This design mimics the original, but requires a matching #6-32 nut to the screw, in order to provide the lifting strength.  I decided against modeling the threads into the plastic, as the force might just rip the threads out.

I tested it in ABS/ASA, but it should work fine in PLA too.  I printed solid, but anything close to 80% infill would work.  Very important, print it on the side so that the stress of the pull doesn't pull the layer lines apart! (It was exported and should import with correct printing orientation.)

Use a 1.5" or longer #6-32 machine screw or similar and a matching backing nut to do the actual pulling.   Use the original 1 or 2 hold down screws (I don't know what size they are - they look like m3 or whatever is close to that in imperial) that fit the flipper.  See pictures.  Hopefully somebody will update in the comments.

Print a backup now, before you need it later!

How it works:  you first remove the screw that holds in the flipper to the shaft.  pre-assemble the #6-32 screw with the backing nut.  then secure the plastic puller to the flipper using the 2 smaller screws.  then turn down on the #6 screw into the shaft until the flipper releases.
