Block — PRPOL

block() is a solid block with holes on all three axes, so parts can bolt together from any direction.

Customizing block with OpenSCAD parameters

block is a solid block of 1 cm units with a hole pattern on all three axes:

block( dimensions = [3,3,3], do_nut_pockets = true, nut_thickness = global_default_nut_thickness, nut_width = global_default_nut_width, nut_clearance = global_default_nut_clearance, chamfer_depth = 1.0, hole_diameter = global_default_hole_diameter, hole_faces = 20, echo_parameters = true );

dimensions	the nominal size as an ordered list of 1 cm units, of the form [i, j, k] where i is the number of units along X, j along Y, and k along Z.
do_nut_pockets	when true (default), nut pockets are cut at the bolt axes so m3 nuts sit flush.
nut_thickness	nut thickness in mm (default global_default_nut_thickness, 2.6 mm).
nut_width	nut width across flats in mm (default global_default_nut_width, 5.5 mm, sized for m3 nuts).
nut_clearance	extra clearance around the nut pocket in mm (default global_default_nut_clearance, 0.2 mm).
chamfer_depth	edge chamfer in mm (default 1.0).
hole_diameter	mounting hole diameter in mm (default global_default_hole_diameter, 3.2 mm, sized for m3 screws).
hole_faces	the number of sides used for the round holes (default 20). Higher values give smoother holes but slower renders.
echo_parameters	when true (default), the OpenSCAD console echoes the full parameter list when you preview or render the module.

If you leave a parameter out of the module call, that parameter will just have the default value. For example, these are all valid module calls:

block(); block([3,3,3]); block(dimensions=[2,4,3], chamfer_depth=0);
