m6 Chair Glides & Risers

New chairs came with rubber levellers but are impossible to move the chair when sitting at the table. The nail-on teflon sliders are pennies compared to threaded ones. The printed adapters will not adjust for level but have a centered pilot hole for easy install of the sliders. As the cushions settled the seat height needed a little boost. The risers on plate two have the same features with a 18mm lift.
