glides for cantilever chair

I designed new gliders for our cantilever chairs because the old ones have all fallen off,

the gliders fit on all armchair legs with a tube diameter of 25mm

there are 3 variants

1. without hole

2. with a 5.1mm hole for an M5 screw

3. with a 6.1 mm hole for an M6 screw

the support part has a diameter of about 30mm, i will glue a felt glider to it

I would be very happy about a like, make and a comment ;)
