Ive talked to my contact and he is willing to make a few sets for extra cash on the side. He says manually it took 4 hours, but if he was to make more he would do it differently and save some time. He said his shop would charge probably ~$300 a set, and since he is making them on the side we would charge between 150 - 170 (plus shipping). I want to try them on my machine before I offer them for sale, but I am confident they will work.

It would be awesome if we could get at least 3 people interested in a set so its worth our time. The price can be reduced to with a larger order.

unextas:
Also, Can 1/4" material be used? Did you use 1/4"?
3/16" (what lulzbot spec says) is harder to find.

I used 3/16", metal supermarkets (thats an actual company hehe) near me had lots of it in stock!

Maybe I should rethink making these sets lol.. I was thinking I'd have to charge $75 or so for a set to make it worth my time, but didn't think people would want to pay that much :) Still think lulzbot could easily order a few more of these from their supplier and save people a bunch of money!

Has anyone else tried these out of plastic?

My plastic ones seem to work fine. There probably is a bit of flex potential there, but the X axis rods and the Z axis rods constrain that somewhat to where I don't think it will be an issue. I would be willing to buy a metal set for $75 if one were available. I would not be buying one at $150 though.

Hmm.. Well I have enough aluminum to make two more pairs. If you do want a pair, send me a PM and we'll get things going. They're fairly small and light so I can probably include shipping to the US/Canada for the $75. I guess I can make it USD75 for the US folks and CAD75 in Canada :)

I'm busy today and tomorrow but could have these made and shipped on Wednesday.

Btw, just to clarify - these would be made from 3/16" 6061-T6, CNC milled with all the holes drilled and tapped as specified.. They will be deburred but not polished or anodized, just the mill finish top and bottom and the machined finish on the sides! If I was making 10 pairs or something, anodizing would be cheap to do, but for a couple of pairs I don't think it's worth it ;) spray paint should work OK if you want them to be black!

Anyway - since it is a CNC, most of the time and effort is in setting things up.. If there were enough folks interested, the price could easily come down further, but I don't know that there are that many folks doing these upgrades! I've thought about putting together TAZ4 ballscrew upgrade kits with all the printed parts, machined bits and the hardware etc.. Not sure how 'kosher' it would be to try to sell something like that on the lulzbot forum ;) I think I'd they wanted people to upgrade, they'd sell the kits themselves! The X end plates are really more suited to be waterjet cut and they end up being much cheaper that way.. I think they cost Aleph Objects under $12 each - in 1500 quantities :D

I actually have a small anodizing setup so I could anodize them if I decided to go that route. One of these days I'll get my CNC mill finished and fully operational heh.

As far as kits go, the way I look at it, is if you are selling something the company itself has not expressed an interest in selling, having that available to people who own those printers is probably a benefit because it increases the options available to the machine owners. I've toyed with similar ideas for various A0-10x upgrades or lighting subsystems too.

At any rate, I'll shoot you a PM here in a minute.

I just printed off a pair of these parts, BUT I would think about purchasing a pair for $50 if the cost got down to it....especially if they were anodized a nice black color :D

If you find 9 more people to order at once, I'd probably do them for $50 (plus shipping!) and I'd consider the anodizing.. But you might have to settle for black spray paint!

I'm in for a set in the $50 - $75 range. Make sure you charge enough to make it worth your while.

Well, the way I made mine and piercet's (just need to finish tapping some of the holes tomorrow and will ship in the afternoon! :) ) I have a single fixture, so it takes quite a while.. Basically cut the inside pockets and drill all the holes on one plate with external clamps, take the clamps off, put bolts through a few of the holes to hold the plate in place, machine the outside. Repeat for each plate.. If I had a tool changer, it wouldn't be quite so bad either! It's not hard work, it just takes a while and keeps me from doing anything else as most operations finish in a few minutes and I need to change tools to get the next one going.

If an order for 10 or more pairs came in, it would be worth while making a bigger fixture so I could cut 2 or 4 plates at a time. That would save me a lot of babysitting the machine and a lot of wasted time changing tools back and forth.. But it would take me a couple hours to make a bigger fixture (realistically, more than a couple... It's one of those things that always seems simpler than it ends up being grrr..).

jebcom, PM me if you'd like a set for $75 - I have enough aluminum to make one more pair that I could ship tomorrow or Thursday. I'm happy with the $75 including shipping and feel it's a fair price for the work they give me, but I also completely understand that they may not be worth that much to most people. CNC milling isn't quite the ideal process for these and there are better ways to make them, just hard to justify without bulk ordering. Even a machine with a tool changer would make these super quick to make, but most machines with tool changers aren't sitting idle in basements waiting for odd jobs to come up :)

Got my new Taz 4 Endplates from unxetas today. These things are very nice! Very clean, no burrs, the tapped holes are clean and true, everything lines up just fine. Definitely much stronger than the plastic equivalent. The only dimensional difference between these and the stock ones were the corner fillets where the center Z nut mount attaches. Unxetas let me know ahead of time that those would be there, and I personally feel that makes the part stronger anyways and is not in the way of any other assembly. Shipping was fast, they were well packaged, I'd do business with him again. My pictures here probably don't do them justice, but here's what they look like before they go on the machine with a printed (home print by me, non Lulzbot official print) for comparison

I'm quite happy with these.
