I’ve remixed microphone holder by Tanato by complete re-draw it in OpenSCAD, so you may customize it as you want.
These particular STL files contain holder of 30mm long with inner diameter from 29 to 32mm, mount base fits M8 nut (outer size between edges is 16mm).
Things added to the design:
adjustable base size to fit any nut
inner diameter of the holder at the ends may be set independently, so the holder may have conical shape
adjustable length and thickness of the holder
I’ve added cogs for better traction at both sides of the joint
there is no necessity in a screw to put parts together – small axle my fix it
There is a parameter called “print_expansion” in all SCAD files: if your printer makes parts slightly bigger (like mine), you may adjust this difference using this parameter. It helps to fit a nut, an axle and a joint without filing or sanding.
Hope it will be useful.
