If i ever lay my hands on a Naked Prototype .. i for sure am going to order a custom wooden hand before doing that...
Btw Dave .. I have experience with vapes that need a glove to hold.. My MW came with a common cotton glove which did the trick nicely ,but always felt kinda like Mickey Mouse when using it.. +
Anyway there are some heat resistant textiles like this one used for whip storage bag.

Whip Slip - Protective Vaporizer Whip Cover - Ranger Green
Protect your glass whip with a Whip Slip. This soft, padded clothe cover is heat resistant to 1000°F. Your whip can go straight from the vaporizer into the Whip Slip without worrying about the hot glass damaging the inner material.
The outer material of the Whip Slip is made from 100% cotton or a cotton blend fabric. A cushioned batting is sandwiched between the inner and outer fabric. The inner lining is a blend of oxidized fiber fabric that allows the Whip Slip to withstand the direct flame of 1000°F without igniting, burning, or melting.
Each Whip Slip is hand sewn, inspected, and proudly made in the U.S.A.
Slip Dimensions: 8” x 2.5”
Whip Slip is designed to cover the glass portion of the whip only, not the hose or mouthpiece. Pattern and colors may differ from image. Whip is not included.
Is 1000 F enough to handle the UD burning heart ? Anyway it is far less expensive than wood/glass/metal
.. + much less trouble to deal with ,afterall you put the dog in the sock ..
