Quick isometric perspective drawing dot grid template - Configurable

It is not a difficult model but there are some important details that must be taken into account so that it prints well. I recommend reading the printing instructions.

Description and operation

This template allows you to create an isometric grid of points quickly. You just need to slide the pencil carefully along the guides and the points will be marked.

I have tried multiple dot templates but they all have major drawbacks. On the one hand, it is tedious to have to insert the pencil one by one for each point. On the other hand, the dots have a very small surface to grip the first layer, making models difficult to print.

This model is optimized for 3d printing and allows you to create all points quickly and easily. Simply slide your mechanical pencil along the lines. Slide the pencil loosely and at an angle between 45 and 30 degrees.

Instead of points, this model uses lines that intersect at different layers. This improves adhesion and reduces seams and retractions. In addition to making printing easier, it prints much faster:

The guide sizes are designed for mechanical pencils up to 0.7mm. 

Printing instructions

It is not a complicated model to print but for it to work correctly it is necessary to correctly configure the height of the first layer.

In the download area there are several folders, each one for a different layer height. Choose the models of the first layer height you want to use. The lower the height of the first layer, the better the template will work. You can print the rest of the layers at the height you want since they hardly affect the final result.

IMPORTANT: The laminator may not make the first layer the same height as the rest. The parameter that must be configured is not the general layer height, but “First layer height”:

Make sure you choose the line height that matches that indicated on the model.

Other recommendations

In order to obtain the best results, I recommend that you also adjust the following parameters:

• Choose a high number of perimeters
• External perimeters first
• Disable “Detect bridging perimeters”

The goal is for most of the lines to be parallel to the main lines of the template. This way it prints much faster and the top layers pass straight over the gaps.

The model works better the thinner the first layer. Also if it is printed on a smooth bed. Your printer needs to be able to produce a good first layer at the height you choose.

Configure it your way

Various template sizes included. But if you need another one, you can generate the one you want from the Blender source file. 

You can configure the following parameters:

• Width
• Height
• Margin from borders to grid
• Distance between dots (dot space)
• First Layer Height (Make sure you choose the same value in the slicer)

Even if you have never used Blender, the process will be easy for you. Simply open the file and in the right panel you will see the parameters. If you don't see them, choose the "Grid" object in the tree view (top right box).

Modify the parameters as you wish and export.

To export, the easiest thing is to have the "3d-Print Toolbox" extension activated. Go to Preferences -> Add-Ons, search and activate the extension.

Finally, simply press "export" in the 3D-Printing panel and an STL will be saved in the same folder as the model:

Limitations

This is my first attempt at creating a procedural model in Blender using "geometry nodes". Additionally, part of the process is based on Boolean operations which, in some cases, can produce incorrect geometry. Therefore you can expect that errors will occur or that not all combinations of parameters will create a perfect model. Please check the model carefully in the slicer to ensure that there are no artifacts or strange things.
