This is exactly like the Dremel Foot from ssd, except that the holding piece is a right angle instead of a flat plate. Both styles should prove useful. I did have to file the notches out just a bit, if you do as well be aware that it is easy to overshoot the sweet spot between easy to slide and "grippy." I am thinking that the head piece could have been bigger, I may come back and revisit that after I have used them for a while. Printed on a Da Vinci 1.0 0.2mm Layers 2 Shells 30% Infill Standard Speed
