Update!

I got a box yesterday with some mysterious contents.

Opening it revealed the table of contents, delivery took exactly one week.

I’m very pleased, this is the exact ebay item i bought

Since images can tell the story better than I can this post will be mostly  pictures.

All included parts scattered on the floor, cat was not included in the box.
For those wondering, these parts were ofcourse themselves printed. Gears are made using PLA filament and the rest are printed with ABS filament.
