I'm looking to replace a panel of my computer mouse with a 3D printed part. I don't want to create a permanent bond (such that it can be changed out in the future), so I was considering something like rubber cement or silicone caulking to affix it. Thought I would check with those more knowledgeable as to the suitability of those options/suggestions for others.

Thanks in advance.

P.S. Not my pictures.

Are the parts both made of PLA? Silicone caulking would be elastic and easy to break but it might also become unstuck on its own since the adhesion to plastics is not great.

Rubber cement would also work in principle but it might not be reversible at all and depending on the solvent and what plastics you used it might damage the plastic parts while the solvent is drying. Acetone can damage ABS plastics for instance.

Would a low-temp hot melt gun work? They can operate as low as 120°C which might be low enough to not destroy the plastic parts.

There's only the one part (replacement part is orange PLA) that affixes directly to the mouse (abs plastic?).

The black part off to the side is the old rubber shell that peeled off.

A glue gun may do the trick - at least it's non destructive enough to give it a try!
