Track Mounted Vertical Tie Down

I recently tried to buy some vertical tie downs for my kayak. Ordered YakAttack brand from Amazon. They sent me a paddle holder instead. I returned it and asked to be sent the right thing. Same thing happened again! I took it as a sign to make my own.

For use with ¼"-20 track bolts like these here and ¼"-20 nuts. 

Print Directions

Tie Down

• Orient tie-down horizontally for greatest strength. Nut slot should be facing straight up!
• ABS or PETG if you can't print ABS
• 0.2mm layer height
• 6 walls
• 4 top & bottom layers
• 65% infill
• tree supports on build plate only
• block supports inside the model where the bolt goes

Washer

• Orient the washer flat on the build plate
• TPU. I can imagine that PLA may work? Or just find a thick rubber grommet
• 0.2mm layer height
• 2 walls
• 3 top/bottom layers
• 25% infill
• no supports

Assembly

1. Slide the ¼" nut into the tie-down nut-slot. In PETG this was a bit loose. In ABS I found I needed to press it quite hard (i.e., punch and hammer)
2. Put the washer over the bolt
3. Insert bolt into bottom of tie down
4. Attach to kayak track and go!
