Powertube 625, rubber bumpers

So, since I got my new electric bike I have treated it like my newborn and just felt really bad when I had to put the Powertube 625 battery on the ground, during the installation/uninstallation on the bike. It's hard to avoid, since a guard has to be mounted/unmounted over the battery.

The sollution was some tiny rubber bumpers, mounted on the rails on the battery.
Now I can put my baby on the ground, without any naughty sand grains scratching it.

It's not a difficult print, I used Bamboo TPU 95A HF, 10% infill.
