Penplotter Uuna Tek 3.0 A1 Magnetic paper-holding bar

Installing the paper is quick and easy with magnetic paper-holding bar to hold the sheet in place.

Instead of using 18 magnets each time to hold the paper, there are now only 6 bars, resulting in improved stability.
Importantly, two bars are positioned lower in angle to prevent the pen from hitting a magnet that would obstruct its return to the starting point.

I used round magnets with a diameter of 1.2 mm (1.2 x 1.5 mm) and rectangular (40 x 4 x 3 mm).
