For anyone not familiar with acronyms (like me), VTOL stands for "Vertical Take-Off and Landing".
Funny nitpick, this definition applies to most drones, because most drones sold are x-copters and do not have wings, they always take-off and land vertically.
This should be "a 3D printed winged VTOL drone"
Yeah it's a strange term because it probably originated relative to fixed wing planes. Ie a VTOL plane. But now multicopters are the predominant species so VTOL can sound redundant to most drone builders today.
