You asked if there was "some way"
and here it is... PROVIDING that your remaining parts DO NOT
have any loose wires in the parts left over...
Below see this tubular stuff called "heat shrink"
... The more it's heated the more it shrinks down in size... Of course there are 'limits' as to how far
it will shrink down so picking the right size is very important.
A common hair dryer will aid you in getting a proper 'shrink' and fit.Because it does shrink, do cut it slightly longer
than you actually need... it's easy to trim to size later.
Sooo... as the Heat Shrink heats, it molds
itself in place and keeps the iron innards
in place too (within the handle and under the shrink)!
No worries about electrical shorts or a bad fit ~ unless you pick on a original heat shrink size that is too large thus causing a loose fit? If you find your heat shrink slipping around "AT ALL"... start over with a slightly smaller size.
Also, as it shrinks
it gets slightly thicker around "
the shrink cylinder outer walls" thus assuring a lasting snug
fit! This also provides a slight measure of protection
if the iron is dropped on the shrink protected area.
Of course your iron will continue to transfer heat beyond
it's "new-formed body" and
your flat iron remains quite useful without worries of rubber or particles imparted to your hair!
Here is what the Heat Shrink looks like... Home Depot may have just the size you need... I suspect it may be a $3 fix!
