Tee Extender for TopGolf / Driving Range

UPDATE 4/6/24: Added V2 version with a hole through the middle to hopefully make insertion easier. This version is a bit more rigid than V1, so I suggest using a lower infill percentage and perhaps less wall lines.

Tired of going to TopGolf or the local driving range, only to have your 460cc driver kneecapped because the rubber tees are too short? Not anymore, with this simple tee insert that raises the ball to the proper height for your driver.

I designed this for my local TopGolf's tees and they fit snugly so not to fly out, but with just enough wiggle room to let you easily make height adjustments as needed. I don't know if rubber range tees are equally sized everywhere else, so fitment might be a little hit and miss. A slight scale tweak in your slicer might help in that regard. See the print settings for ideal print orientation for strength.

IMPORTANT: Intended for TPU only! Do NOT use these on tees that are damaged/torn/visibly worn out. They will not provide enough grip to hold the extender in place. I am not responsible for any injury or property damage caused by improper use of this design.
