Paul's OpenSCAD models and libraries.

Hi! Welcome to my OpenSCAD library. Please feel free to use any of these models - they are all licensed under the Creative Commons 4.0 Attribution Non-Commercial license. This means you can use it, but if you modify it you need to name me, and you cannot sell these designs or things based on them.

Most of these models are parameterised - they are based on constants that can be adjusted.

Primitive and building block libraries

These are the basic functions I use for most of my other modelling.

File: pwlib_boards.scad

Functions to generate cases for PCBs.

File: pw_primitives.scad

Functions:

• rounded_cube(x, y, z, chamfer_rad)

File: gears.scad

A borrowed gears library. Source: https://github.com/chrisspen/gears

Basic tools

File: vacuum_adaptor.scad

For adapting a vacuum hose to an inlet of a different size.

File: water_shutoff_handle_v1.scad

For putting over the thin metal handle on the shutoff valve on our water meter, to give better leverage.

Cardboard perforator

File: cardboard_packing_roller.scad

The bits and pieces to construct a machine that can perforate a piece of standard box cardboard such that it can then be scrunched up and used as packing for things being sent by post.

Dust extraction

File: cone_adapter.scad

An adapter to go from the 100mm PVC pipe I use for my dust extraction system to Marius Hornberger's excellent flexible (but 90mm) dust extractor parts.

File: cyclone_separator_base.scad

An attempt at making a cyclonic dust separator in OpenSCAD. Not very good.

File: dust_extractor_adapter.scad File: square_to_circle_poly_generator.py

The square_to_circle_poly_generator.py program generates a polyhedron that smoothly blends a rectangle into a circle across a given height.

The dust_extractor_adapter.scad file integrates a basic version of this with the inlet and outlet parts that would attach to my Carbatec 2HP dust extractor outlet.

File: dust_extractor_rectangular_adapter.scad

This is an alternate idea for an outlet adapter for the Carbatec dust extractor, where the 'pipe' stays rectangular but curves around from vertical to horizontal in 22.5 or 30 degree steps.

File: dust_separator_inlet.scad

Another idea for a dust separator, based on the horizontal cyclonic separator idea. This would allow the tube from the Carbatec to go into the horizontal separator tube at 45 degrees, to form the cyclone without extra vanes.

File: impeller_basic.scad

A basic attempt at designing a compressor impeller in OpenSCAD.

File: lathe_extractor_fan_v1.0.scad

A fan blades and housing, designed to attach to the housing and drive shaft of a Vicmarc VL240 lathe. This adds a modest extra source of dust capture and movement on the lathe itself, without other equipment.

File: spiral_dust_collector_support_slivers_v1.scad

Experimenting with parts to support the spiral in a cyclonic separator replacement for my current inefficient Carbatec separator.

EV Charging

Parts for holding EV charger connectors and EVSEs.

File: charger_cable_holder_v1.scad

The basic part for a piece that the base of an EV charger connector could sit in.

GridFinity tools

I use the GridFinity reworked OpenSCAD library for actual baseplates and boxes. These are the tools I've made to place the magnets in them.

File: 6x2_magnet_all_in_one.scad File: 6x2_magnet_dispenser.scad File: 6x2_magnet_placer_v1.scad File: 6x2_magnet_placer_v2.scad

Oddments

Things I've made that don't really have a good home anywhere else.

File: cable_patch_end_clip_v1.scad File: cable_patch_end_clip_v2.scad

Clips for a 12-port Cat-5 patch bay that don't get in the way of the cables to be attached.

File: cupcake_holder_plate.scad File: cupcake_holder.scad

Two different systems for pieces that go in a standard food container and prevent cupcakes or muffins from moving around and destroying themselves when in transit.

File: downpipe_mount.scad

A piece that lifts the mount for the downpipe to our eastern water tank up so that the pipe itself sits higher than the sieve.

File: garden_bed_hose_guide.scad

A piece that could be printed in two parts that locked together, such that it could sit on the side of a garden bed wall and guide a hose without kinking.

File: organza_bag_funnel.scad

A basic funnel, designed for filling the specific organza bags I use to sell camphor laurel and huon pine shavings.

File: red_hat_service_award_holder.scad

For those in Red Hat who have received their five and ten year 'puck', this is a much more stable base for it. The award won't fall out easily and it fits it perfectly. Best printed in red, obviously.

File: rob_food_processor_lid.scad

A replacement lid for a friend's food processor.

File: rounded_square_twist_vase.scad

Using the example of the offset 2D function and twist in linear_extrude to make some interesting simple vases. Best with rainbow, bi-colour or tri-colour filament.

File: thundersky_battery_handle_v1.scad

A handle to fit on ThunderSky / Winston Energy 60AH LiFePO4 cells, so that the pack can be lifted as a whole. Currently contains the pinch function for operating on lists of 2D points.

File: tickety_boo_sign.scad

For indicating to other people whether everything is tickety-boo or not.

File: tile_cutter_anvil.scad

A replacement anvil for the tile cutter my partner uses for breaking mosaic tiles.

File: trailer_towball_filler.scad

A part that can fit in a trailer towball hitch, and be locked in place, so that no-one else can tow the trailer.

File: trevor table foot v1.0.scad

A replacement for a table foot for a friend.

File: urban_500_mount.scad

A mount for the Urban 500 bicycle light.

PCB cases

Cases I've made for putting various small PCBs in.

File: badger_temp_sensor_case.scad

For the Badger 2040 W badge with Raspberry Pi 2040 plus eInk screen.

File: caberqu C2C tester case.scad

For the caberQU C2C USB C cable tester.

File: diagonal_box.scad

For a board I can't seem to find any more.

File: LCA 2021 conference badge case.scad

For the LCA 2021 hardware BOF conference badge. Very incomplete.

File: quad_usb_box_base.scad File: quad_usb_box.scad

The parts for a four-port USB charger board enclosure.

Test pieces

Mainly used when I'm trying out ideas before I put them in my libraries.

File: conduit_angle_bend.scad File: conduit_angle_bend_toroidal.scad

Work on angled bends that can attach to standard PVC piping.

File: spring_tests.scad

Testing out both straight and circular 'springs' that use a zig-zag construction. Best printed so that each layer goes along the zig-zag, rather than the zig-zag going up and down across layers.

File: tap_handle.scad

Experimenting with modules that can make tap handles with a shaft and a number of 'lobes'.

File: y_tube.scad

A Y join in a pipe, made out of toroid segments.

Woodworking and workshop tools

File: masonry_drill_rack_v1.0.scad

A basic block to store the masonry drills I have.

File: oscillating_sander_vacuum_adapter.scad

An adapter that fits on the side of the AEG oscillating power sander and directly connects to a vacuum hose for a workshop vacuum cleaner.

File: trend_airshield_battery_pack.scad

Still early experiments on making a replacement for the Trend AirShield Pro battery. The idea is to build in a LiPo pouch cell, a USB charger board, and possibly a regulated 3.6V output board.

File: vicmarc_chuck_gauge_v1.scad

Simple pieces that show the inside and outside dimensions of Vicmarc lathe chuck jaws, at their minimum and maximum extend (i.e. narrowest and widest). Includes writing the dimensions and the chuck 'number'.
