Adding these skis let you do takeoff and landings in the T1 on snow. Use the large skis for loose snow, and the standard skis for harder, packed snow. The tail ski is optional but will help raise the tail on landing so the horizontal stab doesn't scrape or wear down the existing tail fin.
Print the skis on their side with supports. Struts can be printed without support.
Recommend to print in PETG for the strut, and LW-PLA for the skis. Especially if using the large skis. After printing assemble using 1.75mm filament to join the skis to the struts. Cut a piece of filament off your roll. Stick it through the hole (may need to use a drill to clean it up), clip off all but a millimeter of excess and then use an iron or hot knife to melt it so it won't move. I also smeared a thin layer of E6000 over the bottom of the ski to help prevent the layers from separating.
