Ultimate Box Generator by pynej

Version 3.7.1 updated August 15, 2022.Download both files and copy/edit the template to make your boxes. The newest versions are listed first (top two files). Welcome to the Ultimate Box Generator! This is a very complex project that will as its name suggests, create boxes for you. And by boxes I mean boxes, containers, compartments with lids, boxes with many smaller compartments within them, and on and on. This tool is very powerful, but also rather complex. There are over 60 custom variables that can be tweaked with no programming experience, and the possibility of make complex inserts and boxes with varying size compartments with a bit of OpenSCAD scripting. This project was originally inspired by https://www.thingiverse.com/thing:15113 with some code from https://www.thingiverse.com/thing:26596. It has since been rewritten completely and grown far beyond those roots. The screenshots above are just a few examples of the myriad types of containers that can be generated with this tool. With the 3.3.x version there is now a template file that you should copy and modify for you boxes instead of editing the variables in the box generator file directly. This project represents hundreds of hours of coding, tinkering, and testing on my part, so please use it, share it, and feel free to drop me a tip if you like. I am still actively developing features so feel free to make suggestions in the comments. Note: mesh_do_sides_x and mesh_do_sides_y where replaced. Please see the example and update as needed.Note: lid_type=0 is now lid_type=5. Features Current Options There are many parameters and variations. I have tested most options but there are innumerable configurations and its totally possible to generate boxes that aren't printable or structurally sound. Box Types Single Box. Repeating Box with compartments in X and/or Y direction. Walls can be suppressed to make larger compartments. Cylinder, hexagonal, or curved bottom and/or sites to hold bits. You can also combine boxes to generate more complex containers with multiple sizes of compartments and depths that fit flush to lid. (This is done with calls to make_internal_box or by using complex_box but requires OpenSCAD scripting.) Lid Types Standard slide on top. Hinged Lid. Snap on top. (Uses a few inner snaps to make a pressure hold. Stackable boxes. Bottom of one box slides into top of another. Mesh TypesSee the examples section for examples and potential material savings. Solid walls. Single Direction. Cross Hatch. (Two sets Rotated by 90 degrees.) Spines pivoted around the vertical. (Ie to do 80- and 100-degree spines.) Diagonal across opening. (Calculate angle automatically corner to corner.) One large opening in wall, optional rounded corners. May need supports on vertical walls. Honeycomb walls. (Adjustable size and spacing.) Internal Structure None Curved for circular bits on sides or bottom. Angles for hexagon tiles. Uneven bottom so bits don't lay flat and can more easily be grabbed. (Partial, Not Tested) Custom. (You can add make_wall calls or use other OpenSCAD code in the template to add custom structure.) External Structure Top hole/token slot Sides can be omitted with inset, rounding, etc Text Options Text can be applied to the sides, top, and bottom. Multiple lines can be provided manually but lines won't wrap automatically. Text can be raised or inset, and the font, size, and angle can be adjusted. With multiple compartments the text can be changed for each compartment. Depending on the overhang, you won’t need supports. If you do a cutaway on a vertical wall you may. Other Options Repeating compartments. Snaps so boxes stay closed. Openings in sides to save materials. Thumb gripes to ease opening. Openings in compartments for dropping bits in. Support for easily surpassing individual walls from the generated structure for larger compartments. Rounding on box edges and/or internal corners. Tools for make complex boxes of smaller boxes. Future Features More complex box generation with varying sizes of compartments. (Partial with make_complex.) Support for custom wall mesh via custom module. Flip lid like the hinged one but with an external hinge and flush top. Rendering speed improvements. (Partial) Regarding wall mesh's and text, some configurations may needs supports but many can be printed without. Also using a mesh can save from 10 to 30% total martial on the print compared to a solid wall at the cost of some print speed. Regarding print speed, make sure your retraction distance isn't to high. Instructions Customizing Boxes To create custom boxes, download both files to the same location and then make a copy of the Box Template.scad file to work on. Edit this file as needed updating variables and adding code to create custom structure. When you are satisfied with the box save it and use the Render and then Export as STL toolbar buttons to make the solid model. By doing it this in the future you can simply replace the Ultimate_Box_Generator.scad file and re-run your custom file to receive new options and fixes without having to edit anything you have customized.

Better documentation and parameters, fixes for mesh calculation issues, new modes.10/20/2017 - Updated with fixes for lid 0 and some mesh layout errors. Examples Regarding Mesh Options I ran a series of tests on a simple box with lid with various Mesh options for comparison. These slicer tester all used the same settings and generated meshes on the sides and top but not the bottom. (This is how I usual print things, the more solid base help ensure the model is rigid and dimensionally accurate.) Test Settings Print Speed: 75mm/s Layer Height: .2mm Retraction Distance: 1.5mm (This was way to high be default at 6.5mm.) Infill: 13% Supports: Where needed (Test 3 & 4) Results You can see blow that the various mesh options all save a noticeable amount of material and don't hinder print speed. It is of course possible to create mesh's that aren't as efficient but this gives a good summary of the possible benefits.
