This model was made by doogielabs. I just put it through Bambu Studio and uploaded it.

To use, remove the collar and collet from the Dremel so you have only the threaded spindle left. Carefully push and thread over the spindle until full depth is achieved, the tapered part at the end helps with center. The tip acts as filler rod and you add heat into the part through friction. This in many ways works like stick welding, where the electrode also acts as the filler media. There are many parallels to regular welding when it comes to using this. For example, it is possible to burn through thinner walled parts when making repairs. Leveraging techniques such as creating a V shape place with thicker walls around the seams where joints will be made really helps with welding.
