I took a very nice design and beefed it up a little for my needs.
There are 2 pieces to these skids.
The top piece printed from TPU protects the arms and motors.
The bottom piece printed from PETG or harder, adds landing feet and skids for landing and protecting the bottom of your frame.
The two pieces have interlocking pins that need some CA glue and to set overnight.
The skids fit over the arms and need a ziptie to properly secure them (a slot is built in for retention).
The author remixed this model.
