Any idea when they will be available? I seem to have damaged the threads on my flexystruder… ---

Maybe the part is listed in the Flexystruder BOM? [http://devel.lulzbot.com/TAZ/accessories/flexystruder/production\_docs/Flexystruder-V1.1-BOM.ods](http://devel.lulzbot.com/TAZ/accessories/flexystruder/production_docs/Flexystruder-V1.1-BOM.ods) Should have the source for the part as well. ---

Not there. Edit: They are on the Buda BOM, But for manufacturer it just says “MBK”. I’m guessing they mean MBK Machine, which is not a place to get a one-off part. ---

Are you referring to the threaded inserts? If you can determine the size M3 or M4, a hardware supplier like mcmaster-carr or fastenal should have them. Brass seems to be the best choice. Sorry if I’m really off-base in what you’re looking for… ---

I got mine off of AliExpress [http://www.aliexpress.com/item/3D-printer-accessories-Budaschnozzle-V2-0-hotend-Nozzle-threaded-pipe-pipes-Threaded-Extension-for-3mm-filament/2034214785.html](http://www.aliexpress.com/item/3D-printer-accessories-Budaschnozzle-V2-0-hotend-Nozzle-threaded-pipe-pipes-Threaded-Extension-for-3mm-filament/2034214785.html) Kenny ---

Thanks, that’s exactly it. I’m a bit nervous about dealing with a company in China directly. I’d feel better if there were a middleman like paypal or amazon. Not sure I like the idea of giving them my credit card number. ---

When you buy from AliExpress, they collect the money (sort of like PayPal). The seller just sends the items. I do have to admit, however, that when I buy from AliExpress, I use a Virtual Credit Card number. Many Banks allow you obtain Virtual Numbers. If you want to PM me your Name and mailing address, I’ll send you a threaded extension. Provided you are in the U.S., of course! Kenny ---

Thanks for the offer, but I have it working, I’ll eventually need to replace it though, I intend to grab one as soon as they come available. If I get around to upgrading to the new heater that he 5 has, I’ll just put my main Budda on my flexy exctruder. ---

Not brass insert, threaded extension is what I’m looking for. ---

He’s talking about the actual threaded hollow pipe in the Buddaschnozzle hot end that the nozzle and heater block attaches to I think. ---

I would recommend dumping the buda and moving to an all metal hotend like the Hex or E3D… I have had much less trouble since I did that.
