When the Ultimaker 2 finishes its prints the build bed drops to the bottom automatically. To avoid any injury to cats that may be investigating at the time I have added this simple clear door to cover the front hole.

The print is just the hook.  It needs to be screwed to an acrylic sheet.

The nuts are encapsulated in hexagonal holes in the design, to make it easy to assemble.


2015-07-27: I have uploaded a new STL file to the correct scale!

Materials and methods

In addition to the print you need:

1x Clear acrylic: 345mm deep x 310mm wide x 3mm thick.

3x Fixings: M4x15mm machine screws and lock nuts
