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.

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 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!

-

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 -near the extreme positions, where the model needs to be accurate.

-

When the sides are constrained then a circular model is more accurate.

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.:

- -

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(). -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 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.

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().

-

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.

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.

explode(d, explode_children = false, offset = [0,0,0])Explode children by specified Z distance or vector d, option to explode grand children
hidden()Make item invisible, except on the BOM
no_explode()Prevent children being exploded
no_pose()Force children not to be posed even if parent is
not_on_bom(on = false)Specify the following child parts are not on the BOM, for example when they are on a PCB that comes assembled
pose(a = [55, 0, 25], t = [0, 0, 0], exploded = undef)Pose an STL or assembly for rendering to png by specifying rotation a and translation t, exploded = true for just the exploded view or false for unexploded only.
stl(name)Name an stl that will appear on the BOM, there needs to a module named <name>_stl to make it

Sphere

-

Redefines sphere() to always have a vertex on all six half axes I.e. vertices at the poles and the equator and $fn a multiple of four. -This ensures hull and minkowski results have the correct dimensions when spheres are placed at the corners.

sphere(r = 1, d = undef)Override sphere so that has vertices on all three axes. Has the advantage of giving correct dimensions when hulled
