Small Parts Tray

I have wanted a small parts tray for some time, I have searched the web but none really ticked the box.
So I decided to design my own, the first version came out well although a bit industrial having 3mm thick walls and a base diameter of 80mm and a print time just over two hours, then after some tweaking up and down finalised on a light version four with a little over 1mm walls and a 70mm base and a print time just under an hour.
you can scale them up or down, though I wouldn't scale the v4 down as there won't be enough material left in it.

A great way to use up those part rolls of filament kicking about

Sorry, the trays are in different formats obj & stl, I had a senior moment last night and forgot to save v4 rsdoc then realised I exported stl :-(
