To create the handle, make a stencil with sturdy cardboard ... different types of texture to your piece. You can also create texture with a hot glue gun on the outside to create scrolls, swirls ...

That’s particularly problematic for things ... most hot glue sticks might be explored. TPU over-molds, anyone? Or perhaps you can use a printer as an injector rather than the glue gun.

The part that pushes the glue stick into the hot end snapped in two ... Still haven’t found a glue gun you can stick to? Try building your own.
