Replacement Parts??

So I am having trouble with my XYZ Da Vinci 1.0 Pro, the little thing that holds the tubing into the extruder head broke, and I can't seem to fix it. Does anybody know where I can find a replacement for this part? I will include a picture of the part. Thanks!

What part of the clamp assembly is broken? The only thing I see from the picture is possibly the bowden tubing looks a little short for a 4mm OD x 4mm OD, Straight Pneumatic Connector.

This part had a little metal ring with teeth that broke off inside it, so the tube did not stay locked in place. I will look up what you said, the 4mm OD x 4mm OD to see if I can find it thank you!

Your last image is the 4mm to 4mm Straight Pneumatic Union (https://amzn.to/35DhVUK) that typically fails on the Da Vinci Pro. Typically when this occurs the end of the bowden tube going down into the hotend is damaged. For the pneumatic union to work the end of the tube must be a clean straight cut with no damage. In my experience trying to replace the short tube is s very difficult task and many enlarge the hole and tap the plastic with a BSPT 1/8"-28 thread (https://amzn.to/2Lc0K3b) for a PC4-M10 (https://bit.ly/3eLooB3) or PC4-01 NPT (https://bit.ly/3bkeKTf). It is possible to use a M10 thread in the 1/8-28 tapped hole since the threads are so similar.

The metal guide tube at the bottom for the filament sensor does have a small 4mm countersink the PTFE will need to be in for the filament to move as free as possible. Use the natural curve in the PTFe tubing to your advantage; just twist the tubing in the fitting until it goes into the countersink ind push it down in there. After this modification I never put the top cover back since it serves no function. To determine the best length of the tubing coming out of the hotend my only criteria is the union must not come in contact with the top of the printer. Otherwise it causes the union to fail and a horrible racket when printing and as it bangs on the underside of the cover.

If you do not have a tap and die set the GEARWRENCH 75 Pc. SAE/Metric Ratcheting Tap and Die Set - 3887 (https://amzn.to/2Lb25qQ) is a very nice set and a good value for the home DIY user. It does have the BSPT 1/8-28 tap in the set. As an owner of this set my only difficulty with it is the taps are sometimes difficult to remove from the holders, but it is better than them falling out.
