Flexible Articulated Arm

Articulated arm for wall mounting, with various assembly options, for the ergonomic provision of tools, workpieces or shelves.

Extend the arm and attach your own creations and tool holders. Assemble the arm according to your needs, the way you need it. Lengthen or shorten the arm if the reach does not fit your circumstances. 

Use the Slot Nut M5 to attach additional accessories or cables, or to realize your own creation.

If you are missing an option, let me know how I can improve the arm.

Assembly Notes:

In all my tests, I was always able to screw the screws directly into the plastic and had sufficient strength without using threaded inserts.

Hinge (Small hinge similar)

Parts: Base 60x30 Screw or Screw for clamping Alingment Guide Hinge Countersunk Screw M5. Length as required

First use the countersunk screws to attach the base to profiles, the wall or wherever you need it. Then the joints can be attached with the printed screws.

Knob M5, cylinder head screw

Parts: 1x Knob 1x Knob Lid 1x Washer (not always necessary) 3x Locking Piece Cylinder Head Screw M5 (ISO4762). Length as required for hexagon head screw knob (ISO4017)

Slide the washer over the screw and insert the screw into the Knob Lid. Then insert this assembly into the knob. Then secure the lid with the locking piece from the side.

Print Settings:

• See the different examples in download section, especially for print-bed orientation
• I used PETG, PLA will work too
• 0,2mm layer heigt
• 0,4mm nozzle
• 15% infill
• no supports needed

The profiles can be printed in two ways. Horizontally or vertically on the print bed. The horizontal version can be printed faster and is more stable depending on the force applied. Beware of print bed lift-off at the ends. Use a brim

The upright version takes longer to print, but is slightly more accurate and you do not need an brim
