Mr LongARM

So I designed and printed this for my self few years ago when i had tumor surgery donon my leg. I couldnt bend my leg for 40 days (sit or bend down to pick something up)

in 2020 this thing can help to keep distance form any hazards.

Use 20x20 aluminium squeare pipes And M3 Screws as shown on picture.

Use tpu or Flex for Lips inserts (for better grip) (or print in ordinary plastic and glue them if you dont have any flex filament.

Use steel 1mm cable to deliver CLOSE action from trigger to pulley Ropes tend to stretch quickly I used 1mm steel cable.

Use some bungie strings for AUTO OPEN action.
