Over-engineered Golf Tee

When I would play golf my tee would always go flying so I designed a tee that stays in the ground very good with threads. It can tilt at a 13-degree angle! vs a normal one can only tilt at an 8-degree angle 😲. It is adjustable with a nut so every time it is the same height.

Supplies

• Snippers
• Sandpaper
• Calipers
• Flathead screwdriver

Step 1: Cad

First download Autodesk fusion 360 then you are all set.

Step 2: Sketch Body

1. Create a back view sketch.
2. Create a line 50mm in height.
3. At the bottom of the 50mm create a line on the x axis that is 5mm to the left.
4. Create a line 44mm high at the end of the 5mm.
5. Create a line on the 44mm diagonal left thru half of one of the grid cubes(look at the picture)
6. Create a 10mm line connecting the golf tee.
7. Finish the sketch

Step 3: Revolve Body

1. Click create in the top left corner then revolve.
2. Select the sketch.
3. For the axis select the z axis.
4. Angle 360.0 deg.
5. Direction one side.

Step 4: Sketch Ball Holder

1. Create a back view sketch.
2. Start with a 4mm line across the y axis.
3. At the bottom of that line do another 4mm line on the x axis. look at the picture.
4. Create a left diagonal line spaced evenly up that is 5.657mm.
5. Then 8mm line connecting them.
6. Finish the sketch.

Step 5: Revolve Ball Holder

1. Click revolve in create.
2. Select the sketch.
3. Z axis
4. 360.0 deg
5. Operation cut

Step 6: Sketch Tip

1. Sketch a 17mm line on the y axis under the plane.
2. Then a 17.464mm line back up diagonal to the left.
3. Connect them with a line at 3.99mm.
4. Finish sketch.

Step 7: Revolve Tip

1. Select revolve in create.
2. Select the sketch.
3. Z axis.
4. 360.0 deg.
5. Operation join.

Step 8: Thread Body

1. Click create in the top left corner then thread.
2. Select the the long cylinder.
3. Select modeled and full length make sure you have a check mark.
4. Thread type ISO metric trapezoidal threads.
5. Designation TR10x2.
6. Direction right hand.

Step 9: Sketch Nut

1. Create a center diameter circle 10mm next to the tee.
2. Click create then polygon circumscribed polygon start in the center then enter 10mm.
3. Finish sketch.

Step 10: Extrude Nut

1. Hit the e key for extrude select the sketch of the nut.
2. Extrude to 8mm.

Step 11: Thread Nut

2. Size 12mm
3. Designation TR12x2.
4. Direction right hand.

Step 12: Fillet and Chamfer

1. Add a 1mm chamfer to the nut.
2. Add a 1mm fillet to tee

Step 13: Export

Go to file then export STL.

Step 14: Slicing

Print the tee with supports on its side 20% infill

Print the nut with no supports(yes this matters) 20% infill.

Step 15: Printing

1. Filament PLA or ABS.
2. 20% infill.
3. The nut is 15 minutes and the tee is 50 minutes.
