The Festool MFT table is very portable and functional. These clips can help you make use of unused space below that table and can hold paper towels, large sheets of protective paper, masking tape, etc.
They clip on and off with a living-hinge mechanism without damaging the table, and they seem to hold quite a bit of weight without falling off.
Because the fit is tight you can control the “grip” these have on the roll when you install it.
Printing is easy and straightforward. These print without supports as long as you orient the cylindrical portions “up”. I printed in PETG with 3 perimeters and 15% infill at .2 layer height and they work great with stock Prusa Settings on my Mini.
