Amir's Paddling Aid

The specially designed paddle enables Amir to paddle with both hands — for the first time, independently.

It anchors his right wrist and uses the natural muscle tone in his fingers to create a strong, stable grip. This allows him to catch waves without interfering with other key surfing actions, such as getting on or off the board, or standing up while riding a wave.

Print the two TPU parts separately using a 3D printer, according to the settings for TPU material (such as nozzle temperature, print speed, etc..). After printing is complete, allow the parts to cool down fully. Carefully remove the supports using small pliers, making sure not to damage the printed parts.

Send the CAD file for CNC milling.

Use an end mill no larger than 3 mm in diameter.

Secure the polycarbonate sheet on a stable base (wood or MDF) with strong double-sided tape.

Make sure the sheet is flat and machine settings match the material and bit size.

After milling, remove the sheet and peel off any protective film or tape.

For a matte finish, sandblast the surface evenly and carefully.

Attach TPU parts to the polycarbonate edges by fitting each protrusion into its matching hole.

Ensure all fits are tight and secure

Place two Velcro strips, each 200 mm long, precisely one below the other, with the strap positioned between them.

Sew in a rectangular shape twice: once approximately 10 mm from the edge, and a second time approximately 5 mm from the edge (a flattening stitch).

Place the 400 mm Velcro strip precisely above the strap, with the Velcro facing upward (not on the strap).

Sew in a rectangular shape twice: once approximately 10 mm from the edge, and a second time approximately 5 mm from the edge (a flattening stitch).

Note: This time, sew only half of the Velcro strip, leaving the other half completely loose and unsewn.

Flip the strap so that the male Velcro is facing downward.

Now, sew the neoprene piece (160×40 mm) in the center of the sewn half of the male Velcro (centered with a 20 mm gap on each side).

Sew in a rectangular shape approximately 10 mm from the edge.

Position the 50×40 mm strap so that its center aligns with the edge of the loose end of the male Velcro.

Fold it over and sew in a rectangular shape.

First, fold the remaining end of the strap (the side with the female Velcro) in half over itself. (image 1,2)

While it is folded, cut the strap at a 30-degree angle on both sides. (image 3)

Now sew along the edge of the strap, following the angled shape you created, approximately 5 mm from the edge.(image 4)

This is the state the strap should be in at this point (image 5)

And now, move on to the free end of the remaining blue strap, and attach it to the base:

Insert the strap through the designated hole in the base from bottom to top.

NOTE: Make sure the male Velcro is now facing upward. (image 1)

and sew the end of the strap while attaching a D-ring buckle to the strap . (image 2)

With the D-ring inside the strap and the strap inserted into the base, fold the end of the strap inward by approximately 30 mm.

Then, sew the strap as close as possible to the edge of the base.

Sew in a Z-shaped stitch pattern. (image 3,4)

Fold the end of the connecting strap approximately 30 mm inward, with the fold facing inward.

Place it on top of the end of the main strap, and sew in a Z-shaped stitch pattern. (image 1,2)

Insert the main strap through the designated hole on the opposite side of the base (facing the first hole).

Then place the connecting strap on top—without inserting it into the base—folding its end inward by approximately 30 mm.

Sew it in place with a Z-shaped stitch pattern.

The illustration depicts the base flipped upside down (with the top side facing downward):(image 3,4)

Follow the instructions from Step 5, and repeat the exact same steps, with the following changes:

1. Main strap length: 500 mm
2. Male Velcro length: 240 mm
3. Two female Velcro strips, each 120 mm long

Neoprene piece: 80×40 mm

follow the instructions in Step 5 and complete all the steps exactly as described, up to the PAUSE step, with the following changes:

1. Main strap length: 530 mm
2. Male Velcro length: 340 mm
3. Two female Velcro strips, each 170 mm long
4. Neoprene piece: 130×40 mm

Now, attach the strap to the right side of the base (with the top side facing up and the TPU bump facing downward), In the following way:

Position the base so that its front side is facing you, with the TPU bump facing downward.

Place the strap so that the male Velcro is facing down.

Insert the strap through the designated hole on the right side (the smaller one), from bottom to top.

Fold the end of the strap inward by approximately 30 mm and sew it in place using a Z-shaped stitch pattern.
