Get it mate! Prints really well, once you have the right settings (get them on here). No shrinkage, no blobs. It has a higher modulus, you can really notice flexural strength increase. Thinner walls are brittle regardless, so have to design that put abit.

I actually almost broke the robox as i was feeding the XT from the box. slip was alerted and after I struggled to eject the filament I found it had kinked inside. So had to build the stand tonight.

Jack, is it more brittle than ABS (even when you design thicker walls) or less so? I’m using Black ABS at the mo but it doesn’t care for much handling really (I want to be able to drill, screw into (with piloted holes) and assemble parts without them fracturing along the layer boundaries.

[Jack @jack-strong My Robox is a Green Kickstarter Limited Edition]

I think you would prefer it to abs. It’s more rigid, thicker walls are fine, haven’t broken any yet.

[David @dmullerdesign]

@jack-strong What would you regard as ‘thicker’? I’m printing 2mm thick walls with ABS and it’s brittle (in black) delaminates easily with compression along the print lines. I suspect the material may be slightly to blame. But having had a mare with trying to load T-Glase onto a Robox reel, I would like to make sure that it’s going to do the job before I buy any.

Also Jack, can you link to the reel holder and bearings please? Thank you, David.

Well all fractures that I have had with thin areas aren’t walls, so couldn’t comment. However my failures aren’t de lamination related, the material fails, not the bond. Guess it depends what plane your drilling. It is definitely much stiffer than cel abs.

Bearings I got are here:

Also attached a spool feeder image I did, stops the filament unravelling everywhere.

Anything else ?

@jack-strong Just a small digression: I’ve added it here:

http://roboxing.com/robox_accessories_and_projects/colorfabb_robox_spool_holder

Is that OK?

[Jack @jack-strong My Robox is a Green Kickstarter Limited Edition]

Sure thing @click

i will upload central guide stl to thingiverse when I get the chance

Just to note, the stand profile has potruded washer/circles around the bolt bosses, so you do not need to buy washes aswell.

[David @dmullerdesign]

Superb, thanks @jack-strong. I’ll get some ordered tonight.

@jack-strong Did you attach the spool feeder model to your previous post, or was it just a suggested design to copy (no matter if the latter - I can model one of those pretty quickly).

I noticed that they’re now doing carbon-fibre-loaded ColorFabb XT… looks fun, although I expect there would be extruder and nozzle wear issues that others have found with fibre-loaded PLA and other abrasive filaments, so I’m not going to try it.

I have, however, finally ordered the ColorFabb XT sample pack… £19 incl. shipping.
