Pain hook - Muscle massager

Pain hook ( or a traditional Finnish knot hook ) is a massaging device to help you get rid of muscle tensions all around your body.
Used to treat:

• Headache
• Migraine
• Shoulder tension
• Pain between shoulder blades
• Pain in back and upper arms
• Sciatica problems
• Buttock and thigh muscle pain
   

You can find use instructions and more details with a google search “Painhook” “Finnish knot hook”.

Please note, especially for the hook part, prefer stronger, rigid materials. I printed in Sunlu PLA+ and I'd consider that as a minimum.
Using the device is more about technique than strength.
 

This is not the easiest model to assemble, be careful.
Assembly instructions:

• The parts are pre-cut in slicer. Print them as they are.
• Remove supports from the handle and the hook.
• Connect the dovetails using strong glue.
• Secure the handle pins with glue.

• Secure the hook with printed pin and glue.
   The plug will be tight, use glue and a light plastic hammer.

   Make sure the hole is clean of support material, deburr the plug!

   Be careful! Support the opposite hole of the hook against a table if you use a hammer!

• Position the hook and push the bushing trough the hole with the hook lined up.
   The hole is slightly off center, hole is near the edge on the backside of the hook.
• Plug the end caps to the bushing.
