I have a fix for refills! I bought a pack of D1 refills off Amazon (2.3mm diameter). The only problem with them is that the plain diameter along the whole length of the refill allows the refill to fall out the end of the pen. The supplied black cap on the new refills is the same as the Weknife refill. There's no step, like with the original plastic ink tube, to hold the refill in. So, I created a step, with heat-shrink tubing. I used a small diameter tube that would just slip over the D1 refill. I cut it to 3/8 inch long, and positioned it so that the bottom end was in line with the faint joint line where the ballpoint assembly is pressed into the ink tube. You could also measure from the original but the joint line works perfectly on the ones I bought. Apply a quick flame and shrink the tube. If it has moved, you can always cut it off with a knife and try again. . Voila! You have the missing step and a new refill for your Syrinx Titanium!
