I'm building the extruder now and need both the "motor gear" and "drive gear", but can't seem to locate them on the internet. This is what the instructions say: "The motor gear has a pitch circle diameter of 12 mm and the drive gear 36 mm. Any gears with these pitch measurements and 3mm central holes will will do. I used parts CDT0110 (outside diameter 15mm) and CDT0112 (outside diameter 40mm) from Greenweld." [reprap.org] Fair enough, but a search on google pulls up lots of suppliers but without the appropriate specs (bore size too big, too small for M3, etc). Has anyone else found success with a particular gear supplier in the US? If so, where?

It took 19 days for them to show up: 2 to fill the order, 8 to get from Hoddesdon UK to my local post office and 9 days for the post office to figure out how to get the package the remaining 4 miles to my house.

That last bit is a story in itself. I happened to find a slip of paper on the ground a week ago. Apparently, the postal carrier had attempted to deliver the package on the 28th but, since it was an international package, it required a signature. At least that's what the scribbles on the piece of paper appeared to say. I called the toll-free number for the post office and, after repeatedly saying "customer service" at the voice recognition system (in increasing levels of volume), I was eventually connected to a live person. She confirmed that, yes, it required a signature since it was an international package and, no, there was no way to waive that requirement. I arranged for a Saturday delivery. I waited around all day Saturday for the delivery. Nothing. Granted, a tropical storm came through that morning, which might have caused some delivery problems. Saturday evening, I walked up my driveway to my mailbox (just in case) and found the package stuffed in there. Apparently it didn't need my signature after all.]]> degroof Reprappers Mon, 08 Sep 2008 15:38:06 -0400 https://reprap.org/forum/read.php?4,15553,15710#msg-15710 https://reprap.org/forum/read.php?4,15553,15710#msg-15710

It's really hard to get through 3cm of that plastic (hdpe as I was told, unsure right now) with 500W of drilling power.

And I do think it's impossible to bore 8cm long holes (which must be done)
not that my drillpress have a lift close to 8cm... ;)
But I don't think that changing the drillpress would solve the problem at all.
So I'll wait for my friend with his 3kW 800kg drill to make straight holes in the proper positions ;)

But I'm pretty serious about not having any gears (except the ones in the gm3 itself of course)

But there's much left to do for me so I will take care about the extruder later
