Winter / Simulator Golf Tees

Update: January 2021: Newer version (and hopefully more durable) here: https://www.thingiverse.com/thing:4717733

Golf tees for winter and indoor simulator use like Skytrak.
Print using TPU. I used 0.3mm layer height and 20% infill or lower.

One version is 40mm tall (about 1 5/8 inches)
Another version is 45mm tall.

1/2/2020 Update: Added shorter versions (11mm, 16mm and 21mm). Also added an extra long version (50mm = 2 inches). You can cut it down to your desired height.

1/12/2020 Update: Version 2. Removed some holes to them sturdier. Use 20% infill or less. Less infill will make it more flexible and last longer.

1/25/2020 - Version 4 of 50mm. Added some vertical support to make it sturdier.
