Tim, don't get discouraged by what you've been doing.  It's being noticed by I hope many others as well as me.  As soon as I get your PM with your address I'm sending a couple spools and I'll take care of shipping charges because you're helping out so many others.

I don't mind it a bit, Just surprised they manage to sell for that much.

That makes total sense, I think for within the community, if I don't screw it up, I'd do it at cost (Whole whopping $3.00 probably). I do sell some prints and charge per m of filament rather that cm^3, but I'm doing test models for things I hope to sell eventually. I'd like to generate enough for a couple spools of filament here and there.

Man after my own heart... Just enough for a fix... then another... and another... smile

That's why I keep telling people to raise what they're charging for prints.  I started off at half of shapeways price or half of our current suppliers prices when my quality wasn't nearly as close as theirs.  But as I've learned and improved my quality I'm bumping up a bit.  If they don't like my price or shapeways is lower than I want to charge I give that option to the potential customer. 

Early on I asked the question and people said you can legitimately charge for your engineering time but shouldn't charge that much for your printing time because you're not doing anything.   Here's shapeways doing literally no engineering other than orienting and closing open polygons (not even sure they do the closing of poly's I've never uploaded a bad model to them to see)   But the point is they're charging WAY more than any of us would charge for this set of parts, that they are certainly putting on one platform and printing in under an hour.

It was 50.99 including shipping.  But that is including the tensioner arm and both versions of the add on retainer which I'm not using.

I'm in the wrong business. I've been printing and shipping MK4s for free!

Here's a pic

Can we got some pics of the shapways printed mk4? I want to see how nice they came out!  I think there might be a shim you can print (or just reprint the part that is loose) if you can make it through a print.

Your tape idea sounds good as a fix.

  That's what I started to think too.  Tonight when I get home I'm going to try wrapping a bit of tape around the hot end to get the tighter fit.

I think what you're seeing is a difference in technology.  Our printers have a little more ooze than the shapeways printers.  When tek/lawsy did the mk4 they almost certainly took this into consideration and sized it appropriately so it would fit the peek barrel.
