It's very difficult to drive through the snow on a wheelchair.
Some brands designed and sell wheelchair ski, but the price is very high.
Another disadvantage is that a user has to remove ski on the road and put back on snow.

We designed a wheelchair ski that you don't need to remove each time as a small portion of the wheel goes through the blade and gives you an ability to go on any terrain - roll on asphalt and slide on snow.

Printing instructions:

1. You have to prepare STL files first (https://youtu.be/MzoUjUEXP3o).
   1.1 Open UNAWheel_ski_date.SLDASM file with SolidWorks 2017 or newer
   1.2 Press Edit wheel part
   1.3 Press Edit equation
   1.4 Insert your wheel diameter, shaft diameter and a wheel width
   1.5 Press Ok
   1.6 Save as STL (You don't need to print wheel.stl file)
2. Print 2 ski files, 2 support and latch files and 2 more support and latch files in the mirror orientation
   4-5 walls, 4-5 bottom and top layers
   50% triangle infill for the ski
   100% infill for the support and the latch
   Layer height 0.2-0.3 mm
3. Assembly
   3.1 Remove supports if you used them
   3.2 Bend support and ski parts with the heat gun as on pics. Set temperature depending on the material you used.
   3.3 Use 8 M3 DIN 965 (or any other with the flat head) length 8 mm, 8 M4 DIN 7985 screws length depends on the final sizes, 8 DIN 6923 and 8 DIN 934 nuts to assemble all parts.
