This is a model of Rose Tico's electro prod from The Last Jedi, she uses it on Finn when they first met. I've included the full model but I've laos sliced it into 3 parts. For smaller printers you may need to slice it yourself from the complete model.
I will update this listing when I print it myself in the next few days.
I used Fusion 360 and modelled off screen caps and the Visual Dictionary picture.
