1kg Spool/filament Holder

This is a Spool Holder that can be screwed to a wall. There is two files for this, Many apologies but I am new to 3D printing and I have designed this on TinkerCAD and I had a problem with saving the file as a whole so I have separated them. When you open this in a slicer (I used Cura) just merge the arm on the top section of the base. this also makes the model stronger as it gives more of a structural support.
