Josh3ddesign's Nozzle Change Tool, does anyone know why it's gone/where to get the STL?

Hi everyone,

I have come across this tool:

https://media.prusaprinters.org/media/prints/3924/pdfs/3924-nozzle-changer-tool-20-prusa-edition-0ede5902-fa67-40e4-b19c-0e3751834e01.pdf

I can't find any hint all over the internet where or why the files are gone, does anyone maybe know where to still get the STLs?

 

 

Thanks!

Re; Nozzle Change Tool

I would love to make this too

I believe this was discontinued by the designer, because other people undercut his production costs... and provided poor quality copies via places like Ebay...

Metal parts were available from PrintedSolid

I ordered the metal parts from PrintedSolid and printed one. It proved to be cumbersome and I've gone back to the cheap 16mm spanner that came with a nozzle pack.

I'll look for the STLs.

RE: I had the files...

I had all the STL files and assembly instructions...unfortunately the drive they were on was corrupted. I'm in the process of recovering the files. I'll let you know if I recover them, if worse comes to worse I can reverse engineer the design. 

Plus there is some non-printed parts that you need which aren't specified to protect the design.

Older version

The version I built used older STLs without the nozzle grabber part. Not sure if that's so useful or not. Let me know.

Is the shape the same?

It might be, I have the second version printed so it depends whether the handle shape and contour is the same. I think it is... so if I can't recover the files it is a good starting point.

Anyone ever find the stls? I have the prongs but not the printed parts

I just came across this thread while trying to find where my uncle could buy one of Josh's kits. That's a huge bummer that he has stopped producing those, because mine is a huge time saver for me!

I do have some files leftover on my computer (I don't know if they are complete or only a specific version for the "old prongs" I used, but they are still on my computer), but I don't know how to share them in the thread...

There are all kinds of little torque tools that you can print to tighten nozzles.

However, after futzing around with one of them, I've just settled on doing it using a wrench (spanner) to hold the heater block and a socket on a 'breaker bar' to tighten it, using 'two fingers' of pressure, which seems to work about right.

I figure if I need something more precise, I'll get one of the cheaper 1/4" torque wrenches.

Another option to consider is the zcatch tool. I used it before I moved everything over to Dragon hotends and it worked exceedingly well.

Is the zcatch still around?  I can’t find one. 

Don’t trust forum advice.

Their site z-catch.com is dead, so I assume they've gone out of business. Too bad. It really worked well. But in the grand scheme of things the 3d printing accessory business is a tiny market, hard to see how you can sustain a business unless you're a reseller such as printedsolid etc.

I use https://www.thingiverse.com/thing:4575846 ,swear by it, leaves one hand free to secure the heater block and no likelihood of dropping tool onto bed. Also look at https://www.thingiverse.com/thing:4738816 although I haven't felt the need to try it.

A common issue with all these wrenches printed in PLA is that if you're not really quick performing the change, heat will creep from the heated nozzle across the metallic hexagonal vase until it reaches the plastic part of the wrench, softening the PLA enough to deform the tool and render it useless. It happened to me once with a stubborn nozzle which wouldn't unscrew from the hot end. Now I use only all-metal torque wrenches.

RE: Josh3ddesign's Nozzle Change Tool, does anyone know why it's gone/where to get the STL?

It is important that the nozzle change tools I mentioned above should be printed in the material suggested by the designer. As Artur5 posted above, the material must be capable of withstanding the heat (which pretty much precludes PLA) and that the vanes be of appropriate stiffness to provide torque.

On checking I see that the designer specifies PLA+, I printed in ASA. If I understand correctly PLA, which I've never used, is stiffer than most materials, so perhaps I'm undertightening a little. Never the less, printed in ASA it works just fine. And I repeat, is so much safer than an all metal design.

I like Josh’s Changer.  Great design.  I am looking for it, also.  I did purchase BIQU’s Crab Nozzle Changer and It works well also.  It is more durable but not as cheap.
