Why off-the-shelf often fails
Drawers, screens and equipment come in different sizes. A print can be made in exactly the width that fits.
Typical solutions
Drawer dividers, cable clips, under-desk headphone holders, modular monitor risers and small-part trays.
For several workstations
Need 20 identical holders? They can be printed in one colour with a relief logo where it makes sense.
Materials
PLA is fine indoors. PETG is chosen where parts see tension, heat or daily handling.
