I'm not planning to make these for other people. I added the logo for a touch of class

and out of appreciation for the forum.
It actually was a piece of rectangular aluminium tubing were I took of the front, then using a big drill (just above the brush handle diameter) I drilled a hole in the upper part and made incisions towards the end to get the bit of metal out. After using the file on the edges, I placed the cut-open sleeving of an elctric wire around the edges.
For the sandblasting I make a negative cutout of the logo in vinyl (sticker), then I use the sandblast gun on it, and afterwards remove the sticker.
