Ultimate nail handle

I'm going to roof a small cabin. It's no power, so I can't bring my stapling gun and compressor. I am not looking forward to sore fingers after nailing thousands of roofing nails. So I made this. I haven't tried it yet other than trying it on some nails. It works better than expected. The nail is held tight to the handle and it is not sensitive to how your attach the nail. You can even put it in the box and it will possibly auto-mount the nail, but you never know if it will be one or three nails, or if it will be upside down. Magnet is 8x3mm. I recommend the strongest neodymium magnet. You should pause the printer at layer 56 to insert magnet.
