You’ve probably seen my recent post related E3D on an ORD-Bot Hadron (find it here https://plus.google.com/u/0/+FrankHelmschrott/posts/NphfoBJqcHe).

I thought until a better solution comes up I’ll help myself so i quickly designed a mount for the E3D as a bowden variant. And also a mount that holds a Nema17 to the frame. I have some of these cheaps feeders lying around from Robodigg (http://www.robotdigg.com/product/70/MK7-Molded-Drive-Block) - these work quite well for me for 1.75 filament.

I havent built everything together so far as i have to reprint the Nema17 mount (had to finetune a few things for my printer).

As soon everything is finished and works for me i’ll post it to Thingiverse and opensource it. Maybe someone else can use it.

Feedback welcome of course.

Well my personal feedback would be: get some of them, greatest shit of all time :slight_smile:

I’ve been so tired of these nut traps. Of course they’re cheap and at the end they work, but they mostly make the print a little bit harder (though not impossible of course) and also things look better and are stronger with the brass inserts.

Actually these ones are not press fit but temperature fit. I think they call them heat inserts. They’re a little bit hard to get in germany. I purchased them a while ago from a UK company via ebay but they last for quite a while (at least for me). I think McMaster has them but well - we germans don’t have McMaster :slight_smile:

As i said they’re heat inserts - i simply insert them using my soldering iron - that works quite well, and is quickly done.

add: the company i got them from was http://www.insertsdirect.com/ - they’re the manufacturer of these pieces and normally sell in bigger branches but they sold smaller ones on eBay back then - don’t know if they still do. Anyways - they have about any kind of threaded inserts you could think about.

They’re also on Google+ @Insertsdirect.com https://plus.google.com/107115342650503340476/about

yeah might work but i doubt you would be able to place them exactly. mine go in relatively easy and with great precision. You just print the hole in the right diameter (for example it’s 4mm for the M3 inserts, here’s a pic http://www.insertsdirect.com/acatalog/Unheaded_Heatfit_Insert-Heatfit_Inserts.jpg), the first part then fits smooth (the left part on the pic) and the rest just floats in smoothly while warming the plastic. As soon as the plastic hardens it catches that little spikes around the insert. I’m using headless ones so at the end they’re just flat with the surface.

Hey Frank can you put up a video of this set up running on the ordbot hadron ? I have one and am very interested to see it working. Would like to do this modification. Brilliantly done.

I like how you preserve z build height this way. And it’s a nice model.

(Jeff DeMaagd) #7

I too have an Ord Hadron.Yours is definitely one of the nicest mods for the Ord. I’d made a dual direct extruder for it but didn’t preserve the z build height like you did and I don’t have the nice sculpting at all. https://www.youmagine.com/designs/jd-duallie-belt-driven-dual-extruder

I didn’t think E3D would work, but I’ve later concluded that it’s a relatively easy machine job to fit two E3Ds that close together.

I didn’t mean to spam your thread, but it’s neat to see stuff still being developed for Ord.

Very nice. Look forward to seeing the released files!
