Building a printer from a kit

I am collecting parts for a DIY 3D printer and am ready to pick a frame. I already have 5 Nema 17 stepper motors, an arduino mega 2650, a ramps 1.4, and a E3D V6. I need a frame and extruder for somewhere around 7" x 7" x 7" build volume or greater.

I am looking at the Mendelmax 1.5 RepRap kit but that is just the plastics. If the hardware isn't too difficult to find then that could be a good option.

Any other's I should be looking at?

Thanks!

If all you need is a frame why not get some 80/20 or openbeam material and just make your own? you're already committed to doing all the wiring and programming on your own and imo thats the hard part. 80/20 is easy to work with and all the brackets and fasteners you could possibly need are available through their catalog. They have distribution all over the place so there's probably a local industrial supply house that you can get it all from. if not, grainger or msc will get it to your door in a couple days.

Who is the "they" you are talking about?

Not a bad idea but where would I get the plans for making my own frame? I am much more comfortable with the elextronics and programminbg than designing a frame for a 3D printer.

As for the plans, i'm sure a couple minutes of google-fu with keywords like 80/20, openbeam, 3d printer, and frame would net you a fairly extensive list of printers built by others that you could draw ideas from.

Ah, okay. I thought 80/20 was a grade of aluminum or something. I just went to their website and now I see what you were talking about. Thanks for that!

Perhaps I could get the mendelmax kit of plastic parts amd use 80/20 for the metal part. I'll look into that more.

Again,

Thanks!

Or you could just use some round half inch dowls, plywood, screws, and epoxy to make a good frame. So long as you already have the rails, Linear Bearings, Motors, All thread, Nuts, Hot-End, wires, MCU, current drivers, and Zip Ties.

Making a frame is easy for a simple X/Y/Z extruded material printer.
