This is a remix of https://www.thingiverse.com/thing:4238674 I have added support for honeycomb grills inside the holes - new hole types added 3=honeycomb square, 4=honeycomb circle Also added support for ellipse holes not just circles.

WORKS ONLY FOR NEWEST OPENSCAD VERSION - 2019.05.

This is a simple OpenSCAD parametric box generator for electronics I've made for my purposes. It is boring to designing a new box for every DIY project, so a simple box can be generated now without any designing/code writing in a few minutes just by customizer parameters and ruler in my hands. Of course, the specially designed boxes can look much better but when I need a fast one-time solution it is very helpful.

For generator limits testing I've made Orange Pi Lite case just in 30 mins (including hand measuring time) for my Octoprint server and it looks ok despite it is a quite complex object with a lot of holes.

It is a quite simple generator but has some special functions such as custom holes, text, mounts, sleeves, hole arrays. Also, every main parameter of the box can be adjusted too - wall thickness, chamfers, margin and so on. More info about using can be found in the instructions tab.

The number of custom-generated structures is limited but can be easily increased to any number by simple code copy-pasting inside the script. Current version limits are:

4 auto-generated sleeves for cover;
4 auto-generated sleeves for standard PCB (can be turned off);
32 custom holes (circle or rectangle type) with skirts on any box side (cover, bottom, walls);
12 custom sleeves for PCB and other components fixing inside box;
10 custom mounts for box mounting anywhere you need;
10 custom multiline hole arrays (circle or rectangle) for generating cooling ports and other stuff;
10 custom extruded custom strings on any box wall.

Also, I've included some special features like one-click option to prepare a model for printing (no need to move and rotate objects before printing), parts hide/show/move/transparency options and description tab for presets to provide easier identification and version management. Print Settings

PCB dimensions & Tips

Theoretically, this box can be adapted to any screw types with any diameter and length. Sleeves for PCB mounting can be generated automatically by entering the hole shift from X and Y side or manually if the location of holes is more complicated. The box is specially designed for PCBs, so PCB parameters define box size. PCB thickness is defined by 3 variables: thickness, max height from topside, max height from the bottom side. Zero pos for every user-defined object (except text) on the cover and bottom is center of a box; For walls, zero pos X (left/right movement) axis is center of the box and for Y (up/down) axis is center of PCB at half of the thickness position. For easier editing, the PCB dimensions are highlighted with zones (red for top height, blue for thickness, green for bottom height) and can be turned on/off. Examples of use for OpenSCAD customizer (newest version) can be found in "*.json" file (it will load automatically at the start if it is in the same folder with the OpenSCAD script).
