3D part design with OpenSCAD#112: Adding a box lid snap ring.

After taking a look at the box maker in the last post I decided I wanted to add some features to it just for fun and one thing that crossed my mind was a way to snap the lid on the box so I wouldn't need screw holes.

3D part design with OpenSCAD #111- Rounding corners

Quite some time ago I was making a project box customizer but never got around to finishing it, I still need to add standoffs, holes in the lid, etc. But there are a ton of really good OpenSCAD examples available to make project boxes so this one may never get

3D part design with Inkscape and OpenSCAD #110: "sculpting" with OpenSCAD?

intersection() is a really cool way to add some more capabilities to your code, here is an example of how you can take some basic outlines made with Inkscape and carve out a more complex object. I added a few new lines to my existing svg layer code so I

3D part design with Inkscape and OpenSCAD #109: adding SVG import capability to the slotted disk module.

For the slotted disk module I made in the last post to be fully customizable it needed the capability to add any pattern you want to the face of the disk and make the pattern so it could be a hole or extend past the top so I made some

3D part design with OpenSCAD # 108: making a customizable slotted disk.

Being able to make slots that are evenly spaced around a disk is pretty useful for making machines and timing a rotating object. Here is some simple code to make a custom slotted disk. // /*[Slots]*/ slot_number=24;//[1:1:36] slot_depth=1;//[.1:.01:19] slot_width=2;

3Dpart design with OpenSCAD #107: Puffy text.

Recently I was experimenting with a way to expand certain items using a move-able "pillow" shape so I can make some different designs but I hit a wall and wasn't getting anything to work like I wanted it to, usually I will just set the project

3D part design with Inkscape and OpenSCAD #106: Making nice curves.

Sometimes it's nice to smooth out a corner where two objects meet and Inkscape has some tools to make this pretty easy. Here is an example of a pivot arm, I started with a square and made it into a rectangle with the adjustment arrows: I converted it

3D part design with Inkscape and OpenSCAD #105: A handy use for minkowski()

I was experimenting with a way to turn a flat 2D line into a round 3D line and minkowski works great for this, here is the basic code: Path_to_SVG_File =""; Sphere_size=2;//[.1:.01:20] width=.001;//[.001:.01:20] Rotate_x=0;//[0:.01:

3D part design with Inkscape and OpenSCAD #104: Inkscape tip-adjusting multiple nodes at the same time

Once in a while I make a design and I want to round the corners or just specific corners so they have the same radius and Inkscape has a pretty easy way to do this. Here are two objects that I want to make into a wrench, and i want

3D part design with OpenSCAD #103: grabbing an outline from an stl file with offset()

After making the last post I was experimenting with a way to grab an outline from any area of an stl file to use for a fillet or chamfer, it's pretty easy to do this using the offset command and making a frame around a design so you

3D part design with Inkscape and OpenSCAD#102: put a fillet or chamfer around anything.

A few posts back I added an option to do a fillet or chamfer with svg layers imported from Inkscape, but it lacked the capability to do a fillet or chamfer around an individual object on a specific layer, this module addresses that. Minkowski is great for this but takes

3D part design with OpenSCAD #101: Using roof to make a tapered countersink screw hole.

Making a tapered countersink hole for a screw is pretty easy using roof, here is an example: // Taper=true; Taper_adjust=10;//[.01:.01:100] recess_size=10;//[0:.01:100] recess_shape=100;//[3:1:100] recess_depth=3;//[0:.01:100] hole_size=10;//[.1:.01:100] hole_

3D part design with Inkscape and OpenSCAD # 100: Using a non planar slicer to generate gcode for a cnc?

This post is about an experiment I tried to see if I could use a slicer like slic3r or orca slicer to generate gcode for a cnc, the simulations look good but I haven't tried it on a cnc yet and it is definitely a work in progress.

3D part design with Inkscape and OpenSCAD #99: STL to CNC part 2, using multiple layers with gcodetools.

In the last post I set up a basic svg file as an introduction to the gcode tools extension , in this post I'm going to set up a template with multiple layers so it can be used to make different cut depths for different layers and engraving. This

3D part design with Inkscape and OpenSCAD # 98: STL to CNC part 1.

It's pretty easy to use Inkscape and OpenSCAD to turn an STL file into a gcode file for a cnc machine. In this first part I'm going to set up a template in Inkscape so gcode tools is ready to go so you don't

3D part design with Inkscape and OpenSCAD #91: make a pegboard any shape you want.

After I made the pegboard module in post # 61 I decided to make a way to cut it out to any shape I wanted so I could make some cool looking pegboards instead of the plain old square ones. Here is the updated code: /*[Pegboard]*/ show_board= true; hole_number_
