Replacement Clippers Grips in TPU

My silicone handles have been breaking for some time but it only recently occurred to me to replace them with TPU. I found a few other models but they were very different from the originals so I tried to match the contours of the stock handles as much as practical. I also added what I call my “TechHex” pattern because hexagons are the bestagons. 

My intention was to design these to be easy to print without support but this proved to be a bit of an unintentional overhang torcher test. If you're having trouble getting them to print in the original orientation you might consider setting them on their ends with some supports to keep them from falling. Also, if you are having trouble printing both at the same time (TPU can be temperamental) you can just slice one and run the same print twice since they are identical. 

They are designed to fit tight but if they are too tight or not tight enough you can adjust the hole-offset setting in your slicer until it fits how you like. To put the handles on, it helps to have a piece of softwood like pine that you can press the cutters into while you slide the handles on.

To achieve the two tone handles like I have, you only need to swap the filament out around layer 75, assuming you use 0.2mm layers with a 0.3mm first layer like I did.

When removing the old handles, make sure you don't lose the spring. Then, hold onto the opposite handle, keeping your fingers clear of the cutters, and pull from the top and outer most part of the handle, pulling down and away from the arm. Keep in mind where the clippers might go if the handle lets go all at once – wear your safety glasses people! I found through my (many) iterations that this was a fairly safe and easy way to remove the original handles (and the new ones) without fighting too much suction.

Let me know if you have any problems and I hope you'll love this model! Please remember to post a make when you're done! Happy printing!
