Screwless Ender-3 Y axis wheel cover

For all creality printers I had I was always using this "CR-7_Screwless_v-rail_idler_v5"

For the Ender 3 it lacks only one thing - the cover.
So I designed my own. Screws are not needed. Just push with a little force and it will slide into the rail till the end.

Printed in:
eSUN blue PETg, or regular pla
layer 0.2
infil 40 for petg, 25% for PLA.
