This is an adaptation of the lion head by Tevons. It may be good in gold filament rather than my blue prototype. I have found that double sided foam pads or superglue is ideal if this is to go on a pvc front door. I have used super glue to join the spindle to the knocker and it is adequate. The spindle and the circular knocker requires support to keep it on the build plate during printing. The spindle may also require sanding where the supports where for it to fit.
