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.

A simple example project can be found here and more complex examples here.

For more examples of what it can make see the gallery.

The license is GNU General Public License v3.0, see COPYING.

See usage for requirements, installation instructions and a usage guide.

A list of changes classified as breaking, additions or fixes is maintained in CHANGELOG.md.

7_segments

7 Segment displays.

Can be single digits stacked side by side or can be multiple digits in one unit. This is determined by the overall width compared to the width of a digit. Presence of a decimal point is determined by the number of pins. Its position is determined by a heuristic.

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.

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 in a path over toothed or smooth pulleys and calculates an accurate length. Only models 2D paths, belt may twist to support crossed belt core XY and other designs where the belt twists!

By default the path is a closed loop. An open loop can be specified by specifying open=true, and in that case the start and end points are not connected, leaving the loop open.

To get a 180 degree twist of the loop, you can use the twist argument. Twist can be a single number, and in that case the belt will twist after the position with that number. Alternatively twist can be a list of boolean values with a boolean for each position; the belt will then twist after the position that have a true value in the twist list. If the path is specified with pulley/idler types, then you can use auto_twist=true; in that case the belt will automatically twist so the back of the belt always runs against idlers and the tooth side runs against pulleys. If you use open=true then you might also use start_twist=true to let the belt start the part with the back side out.

The path must be specified as a list of positions. Each position should be either a vector with [x, y, pulley] or [x, y, r]. A pulley is a type from pulleys.scad, and correct radius and angle will automatically be calculated. Alternatively a radius can be specified directly.

To make the back of the belt run against a smooth pulley on the outside of the loop specify a negative pitch radius. Alternatively you can just specify smooth pulleys in the path, and it will then happen automatically.

Individual teeth are not drawn, instead they are represented by a lighter colour.

Microswitches

Used for limit switches. Currently only the button type is supported as the lever and roller types are less accurate.

The origin of the switch is in the center of the body. microswitch_button_pos() is the offset to tip of the button at its operating point.

The switch is drawn with the button at the nominal operation point. This actual trigger point can be plus or minus microswitch_op_tol(type).

When the button is released it comes out by a maximum of microswitch_fp_max(type) from the nominal operating point.

Panel_meters

Panel mounted digital meter modules

Notes on the DSN_VC288:

The tabs aren't modelled because they can be fully retracted if the PCB is removed.
The current connector isn't modelled as it is awkwardly tall. I remove it and solder wires instead.

Sheets

Sheet materials. Rectangular with optional rounded corners. Negative radii make a chamfer.

The "Soft" parameter can be used to determine if 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 "Colour" parameter is a quad-array: [R, G, B, Alpha], or can be a named colour, 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.

If 3D features are needed, for example countersinks, then sheets can be modelled in 3D using sheet() and then coloured with render_sheet().

When woven sheets (e.g. carbon fibre) are rendered it is necessary to specify the dimensions again to render_sheet() or render_2D_sheet().

Microswitches

Used for limit switches. Currently only the button type is supported as the lever and roller types are less accurate.

The origin of the switch is in the center of the body. microswitch_button_pos() is the offset to tip of the button at its operating point.

The switch is drawn with the button at the nominal operation point. This actual trigger point can be plus or minus microswitch_op_tol(type).

When the button is released it comes out by a maximum of microswitch_fp_max(type) from the nominal operating point.

Sheets

Sheet materials. Rectangular with optional rounded corners. Negative radii make a chamfer.

The "Soft" parameter can be used to determine if 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 "Colour" parameter is a quad-array: [R, G, B, Alpha], or can be a named colour, see OpenSCAD_User_Manual.

If 3D features are needed, for example countersinks, then sheets can be modelled in 3D using sheet() and then coloured with render_sheet().

When woven sheets (e.g. carbon fibre) are rendered it is necessary to specify the dimensions again to render_sheet() or render_2D_sheet().
