Introducing the HandFlex Pro (0.2V)

The HandFlex Pro is more than just a piece of equipment; it's a tool designed to help you achieve optimal hand and wrist strength. Whether you're an athlete, a fitness enthusiast, or on the path to recovery, the HandFlex Pro is your ideal companion for a stronger grip.

Features:

• The trainer is designed with a comfortable, natural-feeling grip. Its handle incorporates a 21-degree angle, similar to popular pistol grips.
• Adjustable resistance by printing bands with different infill. Replace the bands as your grip strength improves.

Print Requirements:

• - 5x M4 x 22 hex socket screws
• - 5x M4 Nuts
• - Soft rubber-like filament for bands (NinjaFlex 85 TPU or similar)
• - Glue for the middle grip (super glue or Araldite )
• - Recommended PETG for the middle grip. PLA works fine, but PETG has some flexibility and feels much nicer.

Instructions:

Middle grip

1. Print LH and RH of the middle grip. PETG recommended> 25% infill part needs to be strong. Use 0.18-layer height for a smooth finish.
2. Glue the two halves together.

Outside grip.

1. Print LH and RH of the outside grip. PLA works great.
2. Insert the M4 nuts into one of the sides; you may be able to press them in. However, I normally used the tip of a soldering iron.

Rubber Bands:

1. Print sets of 4 bands. Use a soft TPU like NinjaFlex 85.
2. Depending on the type of filament will change the resistance and range of motion.
3. Infill from 10% to 100% as required.
