Parametric clamp. Supplied as an OpenSCAD module, almost all dimensions can be changed.

Customisations include base (enabled / disabled with size parameters). Automatically spaced screw holes on the clamp jaws (enabled / disabled with diameters and optional nut recesses).

Full list of parameters in instructions.


  1. Load design into OpenSCAD

  2. Customise parameters as required.

base : Enable / disable clamp base
base_thickness : Thickness of clamp base if enabled
base_width : Width of clamp base if enabled
ring_thickness : Tickness of clamp ring
ring_inner_dia : Inner diameter of clamp ring
jaws_thickness : Thickness of clamp jaws
jaws_width : Width of clamp jaws
break_width : Width of break in clamp jaws
screw_diameter : Screw hole diameter
screw_count : Screw hole count
nut_recess : Enable / disable nut recess in clamp
nut_diameter : Nut recess diameter
nut_thickness : Nut recess depth
height : Clamp height

  1. Export STL

  2. Print! or if OpenSCAD isn't your thing import the STL into the CAD software of your choice for incorporation into another design.

So. Just did my first remix here. Added holes option for base.


great code. Just printed some clamps. Had to drill holes in the base though. Would be perfect to add base holes option for screws as well.



Great idea . I would love to suggest a possible addition.
On the back side of clamp , make an interface such that the clamps can be secured back to back and locked into place at 90 degree and 45 degree increments thereby connecting two rods together.at 45, 90, etc..
Possible base needs to be designed to intelligently lock in the opposite fit .. Pins and holes with a bolt through middle ?
