Paper towel

The standard size accommodates a 160mm internal (maximum roll size) and a 32mm post diameter (maximum hole size). The medium and small variants measure 140mm and 114mm correspondingly. As for the jumbo version, it boasts a 180mm internal space and a 38mm post diameter to cater to larger rolls.

Once the towel roll is inserted with the end left free, a clockwise spin should automatically guide the end out through the side slot. To tear a sheet, pull upwards from the bottom, towards the right edge of the slot.

Feel free to adjust the holder's height. I personally opted for 180mm to suit my bed, and while I wouldn't go much shorter, a taller design wouldn't pose any issues.

Consider adding three rubber pads or feet to prevent sliding. In my case, I've designated a spot on my workbench for paper towels, contemplating attaching it with double-sided tape to create a semi-permanent fixture for a roll.
