If there’s an opening in the roller tube, into which the screen fabric seems to be slid in sideways, yes you can do it.

If the fabric is glued to the roller tube, you can try it, but you have to mke sure no fabric is left on the tube. This residual fabric would cause bumps in your screen.
I wouldn’t even attempt it, if this was the case. Too much work.

But there’s one thing you really need to pay attention to:
On one side, the spring is locked in the side cap. Removing the side cap will release the spring and all the tension will be gone. Make sure to open the side where there’s no tension first, then pull the tube to the side you just openened. The “locked” spring will be pulled from the locking chamber and unroll.

Doing it this way prevents the side cap from hitting your hands. This happened to be ones and I ended up with a bruised thumb. Like if I hit on it with a hammer..

Also before you start disassembling the mechanism, make sure to check if you can put the tension back and how much tension is required.

Normally, it can easily be done by placing the metal part from the spring (that’s normally locked in place), in the plastic cap and turn to create tension.

So you start with the side that holds the spring. The other side will have a round pin and that’s the part that you put back together after you’ve done the spring side.

If you need more info, let me know!
