Print removal tool handle replacement.

I made these handles to replace the POS cheap wooden handle that came on the set of print removal tools I bought on amazon, I love the tools and the work very well especially for the price, but the handles break very easy so I designed these to replace the stock crappy wooden handles. I did make multiple size hole since they are mostly all different OD for the shaft so you will have match up accordingly. for strength and so they do turn or pull out I took A Dremmel with a cutting wheel and did a vertical notch on the shaft that inserts into the handle and than I heated them up with a lighter before inserting them in to keep them from twisting or pulling out. I'm sure i'm not the first one that ran into this issue so good luck and happy printing. Here is the link to the set I bought on amazon the price is right but you get what you pay for - https://www.amazon.com/Teenitor-Removal-Printer-Painting-Enhanced/dp/B073TRYH1G/ref=sr_1_3?ie=UTF8&qid=1539298305&sr=8-3&keywords=3d+printer+part+removal+tool
