I have created picture frames in which the excretions of the printers can be filled in at the edge.

You will need the glass top of a picture frame of the size 13cm x 18cm or 15cm x 200 cm, a photo of your choice.

The exact dimensions can be found in the table, if your glass pane is wide or longer, you have to adjust the frame in the X and Y axis. I haven't tested whether the stand can be changed with the lid (if someone tests it, please let me know)

If your glass pane is thicker, please shorten the insert in the Z axis.

The photos used are:

Assembly:

First, take the glass plate and place it in the frame

Fill the insert with "your" poop

Place the frame with the glass over it and press the insert against the glass pane from below

Rotate the frame 180° and add your photo.

Presses the desired lid firmly .....
