Safety Guidelines

You are being given an experimental 3D printed assistive device. If you have any problems or concern, or require medical advice, please contact your doctor or Humanos3D.

An upper limb assistive device can improve functionality in some basic tasks like self-care and other daily activities, and can improve body image, but in no way is a substitute for a natural hand. It is designed to provide support, or improve aesthetics.

Tips for Daily Activities

  • Your assistive device should be used as a ‘helper’ to support or stabilise.
  • It is important to think about how to position your assistive device before you attempt to complete a task.
  • Remember to try all activities bimanually to avoid overuse injury.

Lifting and Carrying

Lifting is easiest at waist height. You will notice your assistive device pulling away or pressure on the Velcro if you are trying to lift something that is too heavy. Do not use the fingers of the assistive device to carry. If the palm of the assistive device is facing the ceiling you will find it easier.

Brushing Teeth

Use assistive device to hold the toothpaste while you open it with your other hand. Use the assistive device to hold the toothbrush while you apply toothpaste. Most people prefer to brush with their non-assistive device hand.

Cooking and Eating

  • Remember not to use your assistive device to hold hot objects.
  • Use your assistive device to support. E.g hold the bowl with your assistive device arm while you stir with your sound arm. Use your assistive device to hold/support a jar while you twist the lid with your sound arm.
  • To cut food: use the assistive device to support the food with a fork, while you cut with your sound arm.

Washing Dishes

Hold the dishes with your sound hand due to the limits of the grip strength of the assistive device. Use your assistive device for wiping and drying


Hold the broom in your sound hand and support the dustpan with your assistive device. Move your body with the broom as you sweep


  • Most people find it easiest to put a shirt on before putting on your assistive device. Always put your residual limb into sleeves first.
  • When pulling up pants, use your assistive device to stabilise the pants while you pull with your sound arm.
  • Most people do not find a assistive device useful for pulling up socks due to the limits of grip strength


Use your assistive device arm to push clothing against your body while your sound arm manoeuvres the zipper or button.

Tying Shoes

  1. Start by putting your shoe on your foot.
  2. Cross the laces and complete the initial tuck under with one hand
  3. Make one loop on the assistive device side and pinch it down into the shoe at the top of the loop with the back of the assistive device hand, so the palm is facing upward.
  4. Make a loop on the other side with the dominant hand and pinch between two fingers- index finder and middle finger. With the ring finger and pinky finger, press up on the first loop.
  5. Pass the loop under the other loop, holding away from the end of the loop, so your fingers don’t cross over the first loop.
  6. Pull about ½ inch back on the second loop to create a space for the loop to pass through.
  7. Wrap the end of the second loop over the first loop and pull through the opening.
  8. Tighten the loop by pulling on the non-tail end of the second loop

Holding Objects like a Phone

Always place the object into your assistive device arm with your sound arm first.

You may find a rubber case for your phone useful.

Using Scissors
