Luge

Non functional model of a luge, put it on your writing desk and think of your favorite hobby when looking at it.
Print skids 01.stl twice, print pillars 02.stl twice as is and twice y-mirrored(I achieved best results when printing the pillars as shown in the cura screenshot), print the seat 03a.stl or 03b.stl once. To fix 03b, I used some yarn.
Cut a rubber band, fix the parts and place the knot inside one of the pillars.
