Itty Bitty Double Extruder

[TechMasterJoe]

There has been a fair amount of interest in a hardware kit, so I've been investigating pricing.

What would you want in a hardware kit for the extruder?

• Screws, bearings, pulleys, belts, springs and insulating tape (of course)
• Hobbed bolts?
• Hot ends?
• Motors?
• Z probe servo?

If you have stock MakerFarm-shipped RAMPS electronics, you might also need

• A4988 driver board
• RRD Fan extender

to control the extra motor and print cooling fan.

Everything (except the RAMPS electronics) can be sourced from a combination of MrMetric, MakerFarm, Pololu, McMaster Carr, HobbyKing, Harbor Freight and a couple of Chinese eBay sellers for around $253, including shipping to the US (2-3 weeks). I'll upload a shopping list soon.

I've been investigating volume pricing, and I could probably offer an all-inclusive kit (everything except the RAMPS electronics) shipped Priority Mail in the US for a little less (maybe $230, depending on sourcing).

How much demand would there be for such a kit, or for a cheaper kit without the hot ends and motors?

What would you want in a hardware kit for the extruder? answers

• Screws, bearings, pulleys, belts, springs and insulating tape (of course) = YES to all of that
• Hobbed bolts? = YES
• Hot ends? = NO but if talks with Colin go well, having an option to buy 1 or 2 heads might be cool
• Motors? = Maybe but not really right off the bat
• Z probe servo? = maybe but we can do that for now
• Fans? = Yes

if talks with colin work out hve it as an option like a drop down list check boxes,
with info on the page about whats parts are need for witch models.

most people with 3dprinters (except makerbot owners) have good Google skills and can source the bigger stuff.

Thanks. I think the small hardware is the real killer because you have to order so many small quantities of various bits from all over.

I have a McFadden-dale hardware less then 300 yards from my front door so I don't really need a kit anyone that's been to one knows just how much that place rocks. Tack that on to the fact McMaster Carr's warehouse is 1.4 miles away from my shop. I'm set I can get anything fast. If you need any special part's made for a design pm me I own a machine shop both a real shop and one at home with 26 cnc's in all.

After I get the 12" i3v I might ask Colin if he wants to make a metal ver or if he is OK with me selling a metal frame upgrade I got a OMAX 80X water jet that I don't really use much

I will be producing hotends a little bit like the hexagon with electropolished nozzles soon..running small batch at my costs I think, I can make them for under 20$ my cost so a retail around 30$ complete.
I plan on making the nozzle and the heat break one solid piece of stainless steel and including 4 of them in 3 sizes (.3 for 1.75, .4 for 1.75, .4 for 3.0, .5 for 3.0) by making it a single piece the hotend will work with both 1.75 and 3.0 by just changing the heat brake/nozzle

I don't mean to take the thread off topic, but I just placed an order for my 12" i3v last week and would definitely be interested in a metal/acrylic frame upgrade.
