There are also a lot of 3M products that or for mounting you can find in automotive stores. Basically anything that is a decent name brand, rated for a decent amount of weight and indoor/outdoor use.
If you are 3D printing, maybe make the bottom of the pieces with a little recessed area for the tape to fit in but still make contact. Or use a thinner material like people use on the lightsaber T-track grips. That is if you are worrying about sticking up too high. I've not had an issue with the applications I have used the tape for.
