I think by "two or more" types of haptic motors, you mean linear resonant actuators (LRA) and eccentric rotating mass (ERM)? And then there are exciters or speaker-like actuators that Tass's experiment used. I've had good luck so far with exciters (TEAX09C005-8), but they are relatively la...

The black plastic is a little hard to photograph, so I turned the flash on, but it didn't really help. But here it is assembled: assembled_bottom.png And from the top. Like I said, the finger surface is a little rough, but I think it would be functional if the contactor pin could reach. assembled_to...

I measure the contactor pin to be around 1.2mm below the finger surface, so maybe "several millimeters" was an exaggeration. I measure my contactor pin to be 5.1mm tall, so maybe it's a little short compared to the 5.7mm model, so that could be part of it. Did you leave the foam intact on ...

Maybe there are better ways to do this, but I think one way to make it more printable on FDM would be to separate the finger cup into a separate part that can be glued on. (And make the exciter housing have a flat bottom that mates to it). two_part_housing.png Then we could even print the finger hou...

I just tried this with the TEAX09C005-8 exciter, but I have a few comments: 1) The model is difficult to print on a FDM printer. I have had some marginal luck printing it upside down (finger side down). I cropped off the bottom 1mm so there is better contact with the bed, and then printed with suppo...
