Spool Wall Mount with detachable arm

Simple spool mount with detachable hanger arm. It prints horizontally so it saves time and has better oriented layer lines to withstand filament spool weight. I designed it for my enclosure made from a kitchen cabinet - the detachable arm is in cases when I don't need a spool there a for time being or doing general cleanup, service. They've been working fine for the past months. The arm can be further secured in place with an M3 screw - tightening it down is optional.
