Tilt-arm for mounting accessories

prusaprinters

<p>I needed an adjustable and tilting arm for mounting different little accessories (e.g. a pop-filter, little lights or a little microphone) to a stand. Therefore I made this arm with a indexed hinge and a ball joint.</p> <p>The special thing is that you can create your own adapters for the accessories you need. Just make a octagon-hole (13m side to side) and a hole for a M3 screw in your adapter and you can mount it to the end of the arm. I included an example of an adapter which can rotate and tilt around 3-axes.</p> <p>Both arms are 156mm long (from the mittle of the hinge to the end of the arm). The clamp is made for a bar with 15mm in diameter.</p> <h3>Print instructions</h3><p><h3>Print settings</h3></p> <p><h4>Arm</h4><br/> layer-height: 0.2mm<br/><br/> perimeters: 4 (for greater strength)<br/><br/> material: PETG (for greater strength)<br/><br/> <br/></p> <p><h4>BallJointSocket</h4><br/> layer-height: 0.2mm<br/><br/> perimeters: 3<br/><br/> material: PETG (for greater strength and flexibility)<br/><br/> <br/></p> <p><h4>Ball, knob and fasteners</h4><br/> layer-height: 0.2mm<br/><br/> perimeters: 3 or 4<br/><br/> material: PETG (for greater strength)<br/><br/> <br/></p> <p><h3>Additional needed parts</h3><br/> 3x M6x30 hex-head screw (you will have to shorten one for the knob)<br/><br/> 3x M6 hex nut<br/><br/> min. 2x M3x30 countersunk head screw and 2x M3 nut for mounting the ball and the adapter<br/><br/> additional hardware, depending on your adapter<br/><br/> <br/></p> <p><h3>Assembly instructions</h3><br/> First, push the ball on one arm and secure it with a M3 screw and a corresponding nut in the dedicated slot. Now try to push the ball-end in its socket. You may have to locate the ball and the arm sideways before you cann push it in. Next, you can insert the M6 nuts in the knob and the fasteners and mount them with the M6 hex-head screws like in the pictures. You have to shorten the screw for the knob and also pay attention to put the correct fastener in the correct hole, otherwise you can't tighten them.</p>
