NopSCADlib
An ever expanding library of parts modelled in OpenSCAD useful for 3D printers and enclosures for electronics, etc.
It contains lots of vitamins (the RepRap term for non-printed parts), some general purpose printed parts and some utilities. There are also Python scripts to generate Bills of Materials (BOMs), STL files for all the printed parts and DXF files for CNC routed parts in a project.
Table of Contents
Ball_bearings
Simple model of ball bearings with seals, the colour of which can be specified. If silver they are assumed to be metal and the part number gets a ZZ suffix. Any other colour is assumed to be rubber and the suffix is -2RS.
If a ball bearing has a child it is placed on its top surface, the same as nuts and washers, etc.
Also single bearing balls are modelled as just a silver sphere and a BOM entry.

- If not soft, either tapped holes or a clearance hole and nuts will be used to retain screws.
The "Color" parameter is a quad-array: [R, G, B, Alpha], or can be a named color, see OpenSCAD_User_Manual.
For speed sheets should be modelled in 2D by subtracting holes from 2D templates made by sheet_2D() and then extruded to 3D with render_2D_sheet().

Box
A box made from routed or laser cut sheet sheets and printed profiles and bezels. It can be arbitrarily large
compared to the 3D printed parts because they can be cut into interlocking sections and solvent welded
together. The box panels can be customised to have holes and parts mounted on them by overriding the
definitions of box_base(), box_front(), etc.
box.scad should be used and box_assembly.scad included.
A box is defined with a list that specifies the inside dimensions, top, bottom and side sheet materials, the
screw type and printed part wall thickness. This diagram shows how the various dimensions are labelled:
Normally the side sheets are the same type but they can be overridden individually as long as the substitute has the same thickness.

Butt_box
A box made from CNC cut panels butted together using printed fixing blocks. Useful for making large boxes with minimal 3D printing. More blocks are added as the box gets bigger.
Needs to be included rather than used to allow the panel definitions to be overridden to add holes
and mounted components.
A list specifies the internal dimensions, screw type, top, bottom and side sheet types and the block maximum spacing.
Uses fixing blocks and corner blocks.

Rounded cylinder given radius r, height h, optional internal radius ir and optional angle |
Rounded_polygon
Draw a polygon with rounded corners. Each element of the vector is the XY coordinate and a radius. Radius can be negative for a concave corner.
Because the tangents need to be calculated to find the length these can be calculated separately and re-used when drawing to save calculating them twice.
utils/rounded_polygon.scad Implementation.
tests/rounded_polygon.scad Code for this example.
Functions
rounded_polygon_length(points, tangents) |
Calculate the length given the point list and the list of tangents computed by rounded_polygon_tangents |
rounded_polygon_tangents(points) |
Compute the straight sections needed to draw and to compute the lengths |
Modules

Sweep
Utility to generate a polhedron by sweeping a 2D profile along a 3D path and utilities for generating paths.
The initial orientation is the Y axis of the profile points towards the initial center of curvature, Frenet-Serret style. This means the first three points must not be colinear. Subsequent rotations use the minimum rotation method.
The path can be open or closed. If closed sweep ensures that the start and end have the same rotation to line up. An additional twist around the path can be specified. If the path is closed this should be a multiple of 360.
