Cardboard screw clip and washer
thingiverse
Speed clip backer for cardboard screws, when you need that little extra hold. I printed with a .8 nozzle 110% flow in PLA. works with https://www.thingiverse.com/thing:3867969 and others Works fine and grips the screws well. Hight 3.6mm currently. If you rescale UP to 4mm or 4.5 mm to make it thicker it will be stronger. However it may not be bendy enough to get the screw through. Prints without support for me. The washer gives even more hold and works with stripped out holes.
