Office chair handle

Replacement handle for pneumatic height adjuster stalk used beneath office chairs. It is designed for a stalk with an 8mm diameter.

Best printed vertically, so supports will be required at the base for the aperture (where the metal stalk inserts). Some slicers may wish to support the inset graphics on the upper side of the handle, but this can be eliminated by using a support blocker. A brim would be prudent to give the print additional support when printing like this
