Wanted to mount my lightsabers to the wall without risk of falling.  these clamp with slight pressure. works on lightsaber with a diameter of 38m-42mm. If you use double side tape version, use some superglue on the PLA side. Tape does not stick to PLA so well.  Prints fast, just superglue parts together. if you want to hold your lightsaber horizontally, and turn the logo, send me a message.
