With this plate, the individual PTFE tubes can be identified directly on the guide block. For better readability, a strip of paper is used as background.
Print it with the numbers facing down, no support needed at all.
Assembly:
You need a paper strip with a width of about 12mm
If necessary, clean the slot with a cutter knife
Slide the paper strip through and cut accordingly
The assembly will be easier if the strip is not so wide on one side on a length of about 10cm and then becomes wider. This allows you to push the strip through easier and then pull it on the other side.
The plate should be able to be mounted on the guide block with gentle force and hold by itself
