Flat pack projects

Kirk,

I would also be interested in the dxf file. This shelf would be great in the kid's room.

Just so we're clear here, is this a design that is in the public domain?

Here we go again? Did we not highjack a good thread on the Economy with this same IP issue?

What is there to be clear about? If you want to cut this file to put in your daughter's room for a shelf, I don't think anyone is going to care. However if you plan on setting up shop to sell these by the hundreds then you had better do your due diligence. The fact that there are many companies producing this shelf in many different stores, I would venture to say it is open to Public Domain discussion.

Seems to me a bunch of shopbot members discussing more than one way to skin a cat. There is no conspiracy to steal anyones IP here from what I am reading?

The issue is not the discussion over design or whether someone cuts a copy to hang on their own personal wall.

The issue is that in this thread there are at least two design files offered with direct download links: these user-uploaded files are afaik hosted by Shopbot Inc, since they host the forum. Through no fault of itself, shopbot inc could as such be implicated in some form of rights infringement.

Now, I don't think this specific design is owned by anyone: I haven't seen any such notices in any case. And even if it is, realistically speaking nothing is going to happen anyway, no one is going to bother about some cnc enthusiasts reverse engineering a design.

But, if IP is treated cavalierly by us in this forum, there might come a day when someone decides to bother. At that point, Shopbot will have to decide what to do about the forum. Keep it open but disallow file sharing? Or close it down from their end, so that there's no formal ties between shopbot as a company and the forum?

so you mean I shouldn't have just made and sold 10,000 of these to Wal-mart?

A round watermelon can take up a lot of room in a refrigerator, and the usually round fruit often sits awkwardly on refrigerator shelves. Smart Japanese farmers have forced their watermelons to grow into a square shape by inserting the melons into square, tempered glass cases while the fruit is still growing on the vine.

Danny's lost it


My grandfather was trying to grow square tomatoes in the 70's (as were countless others, I'm sure)

I would like to assume the sky is still intact, until we see pieces falling. Why highjack threads with what if's?

There has been so much interest in this shelf design that I went back and re-created it from scratch with all the mathematical formulas, rather than a graphical solution.

The design now has the ability to display up to 4 additional shelf elements beside the center shelf, with an option for 3 or 2 side shelf elements instead. Open the Spherical Shelf4 / 3 / or 2, depending on the shelf construction. I quit at an additional 4 side shelf elements as the shelf dimension for the largest shelf exceeded 96" at this point.

To use this design, download and install the free Xpress version of Alibre Design.

1. Open the “spherical shelves.AD_PRT” Alibre Part file and modify the CAPITALIZED variables to suit desired shelf configuration. Sometimes it takes a little experimentation to get the shelf configured the way you want it. Open the Equation Editor using the f(x) icon on the far right; TOOLS > EQUATION EDITOR; or Ctrl+E.
