Best cat toy, most fun, zero print time

Warning - you cat will bring these to you at all hours of the day to play with them.  Make 1 for each cat - you can play with 2 cats at the same time.

Make instructions:  Requires a soft and flexible TPU material - the best I have found is Shore 85a Ninjaflex.  It is tough, can take pulling and biting, and lasts a long time.  Print time is ZERO.  You only have to cut off 4 feet of filament and use it like pulling a string.

History: I have made several TPU cat toys.  They love the soft feel.  One day I saw a model of a bent string - the model folds all over the print bed and prints a thin curved tail with a small mouse on one end.  I tried it and it was stiff, the bends didn't unkink when hanging or pulling.  So I said “hey, why print string when the TPU starts out that way!”.  So I cut off 4 feet and compared the “cat reaction”.    Besides the ninjaflex spider - which the cats throw around and put in their water dish, this one gets seal of approval.

Data driven results:  Of all of the toys I have made for the cats, this is the one that the cats bring me in the middle of the night “Play with me please” Meow! Every morning there are two of these sitting at the side of the bed where I put my feet down.   Pictured is our male cat Steve - who just brought me the string toy and convinced me to enter this toy in the cat toy contest.   

BONUS Print:  Since publishing a file requires a model or print file - and this cat toy requires only 3D filament and no time with the printer, there is no model.  But for your satisfaction, I have uploaded favorite spider toy model.  Scale it so the spider is about 2 inches across - and print it in Ninjaflex.  Your cat will love carrying it around and killing it in hours of self play.
