Charge your FitBit Charge 5 or 6 directly on top of the USB power supply. The Europlug holds the charging stand and at least for Schuko outlets it fits between the plug and the outlet.
Perfect for the wall outlet in the bath room.
This is a remix of this great stand: https://www.printables.com/de/model/354285-fitbit-charge-5-stand
I have just added the holder for Europlugs.
No supports needed for printing.
