mount /home/pi/Downloads in external storage

I am using Raspbian Stretch Lite image as a basic setup.
Now I want to do a custom mount point where the downloads will be placed.
So I have this another 64GB USB flash drive and I want to automatically mount at system startup to the /home/pi/Downloads.

This is how I succeed.

Look all mounted IDs:

sudo blkid

Note down PARTUUID for /dev/sda1:

/dev/mmcblk0: PTUUID="cd33d910" PTTYPE="dos"
/dev/mmcblk0p1: LABEL="boot" UUID="109A-9113" TYPE="vfat" PARTUUID="cd33d910-01"
/dev/mmcblk0p2: UUID="673b8ab6-6426-474b-87d3-71bff0fcebc3" TYPE="ext4" PARTUUID="cd33d910-02"
/dev/sda1: UUID="8d4fdcd3-d118-4056-91b1-0e8cf9e62bc0" TYPE="ext4" PARTUUID="6d255a34-01"

Edit file system tab:

sudo vi /etc/fstab

Make sure you add extra new line at the end:

proc            /proc           proc    defaults          0       0
PARTUUID=cd33d910-01  /boot           vfat    defaults          0       2
PARTUUID=cd33d910-02  /               ext4    defaults,noatime  0       1
# a swapfile is not a swap partition, no line here
#   use  dphys-swapfile swap[on|off]  for that
PARTUUID=6d255a34-01 /home/pi/Downloads ext4 defaults 0 1

I the fstab has this line with my new device than I can mount this additional storage instantly with:

sudo mount /home/pi/Downloads

After reboot make sure the pi is owner:

sudo chown pi:pi /home/pi/Downloads
