Slot Bracket — PRPOL

This is what is generated from slot_bracket();.

Customizing slot_bracket with OpenSCAD parameters

slot_bracket is the general-purpose transition part for off-the-shelf components. An m3 screw rides in its slot and a captive m3 nut sits in its pocket, so the bracket can be slid and rotated into position before being tightened down.

If you need smaller screws than m3 to mount a component, just change nut_width to match whatever nut size you need. For example, Raspberry Pi boards mount with m2.5 screws. Suggested values: nut_width = 5.0 for m2.5 nuts, and nut_width = 4.0 for m2 nuts.

Here it is called with every parameter spelled out:

slot_bracket( slot_length = 8, slot_width = global_default_hole_diameter, nut_width = global_default_nut_width, nut_clearance = global_default_nut_clearance, overall_width = 10, slot_wall_offset = 3.5, plate_thickness = 2.5, overall_height = 8, nut_ceiling_thickness = 2, chamfer_depth = 0.75, echo_parameters = true );

slot_length	slot length in mm (default 8).
slot_width	slot width in mm (default global_default_hole_diameter, sized for m3 screws).
nut_width	m3 nut width across flats in mm (default global_default_nut_width).
nut_clearance	added to the nut width where the nut pocket is cut (default global_default_nut_clearance).
overall_width	the bracket width in mm (default 10).
slot_wall_offset	wall thickness between the slot and the outer edge in mm (default 3.5).
plate_thickness	plate thickness in mm (default 2.5).
overall_height	the bracket height in mm (default 8).
nut_ceiling_thickness	the thickness of material above the nut pocket in mm (default 2).
chamfer_depth	edge chamfer in mm (default 0.75).
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:

slot_bracket(); slot_bracket(slot_length = 12); slot_bracket(nut_width = 6, nut_clearance = 0.3);
