# 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, DXF files for CNC routed parts in a project and a manual containing assembly
instructions and exploded views by scraping markdown embedded in OpenSCAD comments, [see scripts](scripts/readme.md). A simple example project can be found [here](examples/MainsBreakOutBox/readme.md).
For more examples of what it can make see the [gallery](gallery/readme.md).
The license is GNU General Public License v3.0, see [COPYING](COPYING).
See [usage](docs/usage.md) for requirements, installation instructions and a usage guide.

## 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.

## Batteries
Actually just single cells at the moment, shown here with mating contacts in place.
Note that the [Lumintop LM34](http://www.lumintop.com/lm34c-usb-rechargeable-18650-li-ion-battery.html) has a built in charger with a USB socket and two LEDs.
The battery length includes its contacts and the origin is the centre of that length. As well as drawing the battery and contacts there are functions
exposing enough information to make a battery box.

## Belts
Models timing belt running over toothed or smooth pulleys and calculates an accurate length.
Only models 2D paths, so not core XY!
To make the back of the belt run against a smooth pulley on the outside of the loop specify a negative pitch radius.
By default the path is a closed loop but a gap length and position can be specified to make open loops.
Individual teeth are not drawn, instead they are represented by a lighter colour.

## Cable_strips
A strip of polypropylene used with ribbon cable to make a cable flexible in one direction only.
Modelled with a Bezier spline, which is not quite the same as a miniumum energy curve but very close, epecially

## Sheets
Sheet materials. Rectangular with optional rounded corners. Negative radii make a chamfer.
The "Soft" parameter can be used to determinesif the sheet material needs machine screws or wood screws, e.g.:
* If soft, wood screws will be used, with a pilot hole.
* 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](https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#color).
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()```.
Note that modules that drill holes will return a 2D object if ```h``` is set to 0 to facilitate this.

## 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 ```use```d and `box_assembly.scad` ```include```d.
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 ```include```d rather than ```use```d 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.
* An optional name can be specified to allow more then one box in a project.
* An optional list of fixing blocks to be omitted can be given.
* Star washers can be omitted by setting the 11th parameter to false.
Uses [fixing blocks](#fixing_block) and [corner blocks](#corner_block).

## Corner_block
Corner brackets using threaded inserts for fastening three sheets together at right angles.
Defaults to M3 but other screws sizes can be specified provided they have inserts defined.
See [butt_box](#Butt_box) for an example of usage.
Note that the block with its inserts is defined as a sub assembly, but its fasteners get added to the parent assembly.
Specific fasteners can be omitted by setting a side's thickness to 0 and the block omitted by setting ```show_block``` to false.
This allows the block and one set of fasteners to be on one assembly and the other fasteners on the mating assemblies.

## Flat_hinge
A parametric flat hinge. A piece of filament can be used for the hinge pin.
The width, depth, thickness, number and type of screws, number of knuckles, knuckle diameter, pin diameter and clearance can all be varied.
A margin between the screws and the knuckle edge can be enforced to allow the hinge to bend all the way back to 270° from closed.
Opening the test in OpenSCAD with its customiser enabled allows these parameters to be played with.
Note setting ```thickness1``` or ```thickness2``` to zero in the ```hinge_fastened_assembly()``` removes the screws from one side or the other and
setting ```show_hinge``` to false removes the hinge.
This allows the hinges and one set of screws to belong to one assembly and the other set of screws to another assembly.

## Offset
3D offset using `minkowski` with a `sphere`, so very slow if `$fn` is not kept small. The offset can be positive or negative.
Can be used to round corners. Positive offsets will round convex corners, negative offsets round concave corners. To round both use [`round_3D()`](#round).
If `chamfer_base` is true then the bottom edge is made suitable for 3D printing by chamfering when the angle gets shallower than 45 degrees.

## Round

the angle gets shallower than 45 degrees.

## 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.

## 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.

Bill Of Materials generation via echo and the ```bom.py``` script. Also handles exploded assembly views and posing. Assembly instructions can precede the module
definition that makes the assembly.
The example below shows how to define a vitamin and incorporate it into an assembly with sub-assemblies and make an exploded view. The resulting flat BOM is shown but
heirachical BOMs are also generated for real projects.
