•only had yellow filament,but should look quite good in black and red as in the first pic

•I made them thicker than the previous, these are 1.2mm thick ,not .8mm

•designed to use a 1.5mm screw to lock it in place

• with small "grip" pad on the bottom to stay on the build-plate while printing, just cut/brake them once finished

• with .2 mm of play between the red and black part, just scale up a bit the red part in your slicer if it doesn't fit properly
