Prusa Quad

prusaprinters

<p>Upcycled Prusament spool used as a quadrotor frame.<br/> The 3D printed propellers are only placeholders and prevent the quad from taking off at the moment (very unbalanced and probably not strong enough).<br/> The clearance between the motors is only enough for propellers up to about 90 mm in diameter.<br/> Any common ESCs &amp; FC with standard hole spacing (30.5 mm, M3) should fit. Motor mount has mounting holes for M2 screws 12 mm &amp; 16 mm apart.</p> <p>UPDATE 1: Due to delivery issues of normal propellers with the required size, I further investigated and tested 3D printed ones. The 6 bladed propellers that I am using currently is based on a Thingiverse design by bigcnc (<a href="https://www.thingiverse.com/thing:990825">https://www.thingiverse.com/thing:990825</a>).<br/> During my first tests I managed to float around, but I'm unable to leave ground effect. Next try will be with a newer and lighter 4 cell battery instead of my 10 year old 3 cell battery.<br/> Video: <a href="https://youtu.be/BzlaTFKo_qA">https://youtu.be/BzlaTFKo_qA</a></p> <p>UPDATE 2: First successful take off with the motors mounted slightly further outwards. Same propellers and same battery as before. Unfortunately, one of the printed propellers exploded after a few minutes of flying (not on video).<br/> Video: <a href="https://youtu.be/UFTagVg0fL4">https://youtu.be/UFTagVg0fL4</a></p> <p>UPDATE 3: Motors are now mounted even further outwards to make room for some larger propellers. The correct size propellers have still not arrived.<br/> Video: <a href="https://youtu.be/D_PUkKUAtcs">https://youtu.be/D_PUkKUAtcs</a></p> <p>UPDATE 4: I have added a camera mount, so you can now also fly the drone with FPV goggles.</p> <h3>Print instructions</h3><p>Printed in PLA with some supports, mostly on build plate only.<br/> Easy way to generate reasonable supports is by using PrusaSlicer's <em>FDM Support Editing</em> feature and autoset them by angle.</p> <p>Some nuts need to be inserted mid print, hence remember to insert pause commands at the appropriate layer height.</p> <p>Depending on whether you have suitable propellers available, only some of the parts are required to build the drone.<br/> If you have small enough propellers or you want to print your own propellers (<strong>propeller6.stl</strong>), only use <strong>motor_mount.stl</strong>.<br/> If you want to use regular 5 inch propellers, use <strong>motor_mount_arm.stl</strong> and <strong>motor_mount_fix.stl</strong>.</p> <p><strong>Additional parts required:</strong></p> <ul> <li>1x flight controller</li> <li>1x power distribution board (optional)</li> <li>4x electronic speed controller</li> <li>4x brushless motors</li> <li>4x propellers (optional)</li> <li>1x battery (4 cell lipo, not too heavy)</li> <li>1x transmitter and receiver</li> <li>1x XT60 battery connector</li> <li>some M3 screws, nuts, washers and standoffs</li> <li>some wire</li> <li>zip ties</li> <li>hook and loop fastener (to attach the battery)</li> </ul>
