Qidi Tech 1 - Replicator 1 clone

Of course you haven't...
Almost everything I have printed needing glued together has been done with superglue. And not a single thing has come apart yet. Some things have been well tested too.
Don't know what to tell ya. Only thing I can think of is the parts are not going together well enough for glue to create good bond.

I tried to compensate for poor design choices by gluing a part back together which had broken under stress. (You all know how this story goes.) First I used super glue, a Loc-tite Ultragel variety, it appeared to work but came apart under mild stress. I next tried acetone on both surfaces, waited a few seconds and then forced them together for 5 minutes with mild finger pressure. It seems to have worked, at least long enough to get the assembly together. The process of assembly was actually the stress factor, so it will hopefully remain functional in place. At least until I have to take it apart and reassemble it. ;-)

Here is my spool roller setup. This is one side and the parts to put it together.

Looking good W! But you're gonna be the slowest guy at the roller rink in those.

Seems to be more drag than I anticipated when skating!!

Here is the finished assembly. By changing the plate you can accommodate different width spools then this will sit on mounting rails that attach to the bottom of the box. Pretty modular design.

I think those would fit me perfectly, look out Roller Derby fans...

I promise this is not a trick question: How long should the PTFE tube that is inside the QiDi extruders be?

I just checked the half dozen I had accumulated from QiDi with spares etc. They measured between 30.3mm and 34.2mm with an average length of 32.3mm. The length apparently is not that critical? Or are these supposed to be trimmed to length when installed? What is the right number?

No idea but I am thinking of switching to the Loctite brand next time but I rarely need to glue parts together.

This is why I do everything with pegs. Of course that don't really help with something that breaks.
I have never had good luck with using just acetone to glue parts together. However I had some luck with with making very runny ABS slury to glue stuff together. Its just a pain to work with, like messing with bondo. You gotta be on point and have no time to correct mistakes if any are made. Course ya dont gat much time with superglue either..but its far less mess.

Oddly enough I have had far better luck with generic off brands of these glues than any namebrand (including Loctite).

The one I have found that works best so far is actually the Wal-mart brand...what most would typically take as a cheap knockofff.
They come 4 tubes to a pack, packaging is mostly yellow. The tubes are black with little yellow band up by the tip. They say only 'Super Glue' on the front of the tube.
Can't even count the number of times I passed these right over trying the various name-brand option. Send my wife to get supplies one day, she brings me this glue back, have only purchased this type since.

Ha Ha! Just bought some of that yesterday.

The LocTite came from Sam's Club. It's 4 bottles for $8 or so, 2 standard viscosity bottles and 2 ultra gel. I typically use the ultra gel as it is easier to manage where it flows, and I can better avoid gluing myself to the part. You press on the flexible sides of the bottle to dispense drops from the tip, and re-capping the bottle works surprisingly well too.

See I had been using the Dollar Tree Superglue, and Crazy Glue since they are not knock offs but the real deal I grew up with but they suck. Hell, I can't even get them to work on plain "non printed" plastic either. Oh, I can get them to stick my fingers together though but not much else (thank goodness for Acetone), lol. I tried the gel and the liquid but both sucked equally well.
