Some time ago I used to print out printjobs on a task sheet A4 paper and had a lot of MicroSD-cards (pre-BambuLab). To assign the jobs to the printers and keep an overview on currently running jobs I wanted to attach the worksheets directly next to the according printer.

Hence I added space for a 10mm magnet to be able to stick it to the shelving. On top there is a slot to put in a MicroSD-card and the clip holds more than just a sheet of paper
