Piper 2 - T-Rex 5015 Radial Fan Mount

prusaprinters

<p>The standard axial fan design did not offer enough airflow/cooling for high-speed/higher temp PLA printing on the Piper 2. I didn't want to re-invent a fan cooler nozzle just yet, but needed the air flow that radial fan's produce.</p> <p>Packaging is a challenge since there is less than 25mm to position a vertical fan to either the front or the back of the Piper 2 X-Carriage.</p> <p>With the suggestion of another Piper 2 builder, I'm using the T-Rex MK3 fan. I've asked the T-Rex designer if he could make the mount hole a little smaller and extend a flange so the 5015 fan can snap into the nozzle. My tests have been good with the current T-Rex MK3 design.</p> <p>Yellow part is the fan/cooler nozzle mount</p> <p>Red part is the T-Rex MK3 Nozzle : <a href="https://www.thingiverse.com/thing:2022857">https://www.thingiverse.com/thing:2022857</a></p> <p>5015 Radial Fan (12v, 24v, and 5v options): https://www.amazon.com/gp/product/B07DB7DLMM</p> <p>Purchase Parts:</p> <p>6-32 x 3/4" taper head screws w/nuts. I used 1" long screws cut down to 3/4" long</p> <p>6 x 3/8" sheet metal screw - holds mount and T-Rex fan together.</p> <p>Note: Round head screws may scrape on the gantry EMT pipe.</p> <p>T-Rex is centered to E3D nozzle, about 1mm up from Z0 and about 13mm back. T-Rex nozzle directs air flow down on print, not across the top of the nozzle.</p> <p>Benchy Images - Left hand benchy is T-Rex and 5015 radial fan, right hand bency is axial fan cooler. Both printed at 150mm/s and 228C on a heated glass bed.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Anet A8</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>Doesn't Matter</p></div> <p><strong>Supports:</strong></p> <p>Yes</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2mm</p></div> <p><strong>Infill:</strong></p> <p>25% to 35%</p> <p><strong>Filament:</strong></p> 3D Solutech PETG <p>Real White</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>You may want to add supports just for the angled arm.
