prusaprinters

<p>I received my KP3s which came with Direct Drive as standard, as I wanted a second printer but a smaller one compared to my Ender 5, unfortunately build quality isn't great on the hotend unit, but it does have some positives on the rest of the frame.</p><p>The first thing I wanted to replace is the hotend setup with it's DD mash up. So I got myself a BMG/E3d V6 Clones but needed an adapter to fit on the Linear rail on the X Carriage.</p><p>After looking around decided to make my one, and here it is.</p><p>I would say this is currently a Work In Progress as I'm printing the parts and ensuring design is as good for others as it is for me.</p><p>With this design the bracket adapter does not need to be remixed if you want to change the fan type or shroud, also if you do not use a BLTouch this does not needed to be printed.</p><p>The Fan mount for the 5015 blower and the BLTouch mount can be adjusted up and down by 2mm in it is too high or too low for your setup.<br>My current setup uses the existing fan that came with the E3d V6 clone, but plenty of adapters to increase it to a bigger fan.</p><p><strong>Update 02/05/21</strong></p><p>I've noticed that I had lost bed size on X axis and Y axis, so to fix the X axis I've added a new limit mount for a M3x20mm screw so that you can adjust it and gain all the 180mm of the X axis, unfortunately it seems Y axis we lose about 8.5mm.&nbsp;</p><p>Still trying to work out design tweaks to give the full 180mm length, any feedback is welcome.</p><p>&nbsp;</p><p>BLTouch Offset values:</p><h3>define NOZZLE_TO_PROBE_OFFSET { 22, 3, 0}</h3><h3>Print instructions</h3><p>Printed this with 40% infill on PLA, but you should be USING PETG for this as it will be close to the hotend.</p><p>The Fan mount can be printed without supports, however it depends how good your printer is tuned for bridging.</p><p>Make sure you flip the X Carriage adapter as there is 1mm square space for the Nema 17 motor.</p><p>The Fan shroud make sure you lay it flat at the bottom, so it will be at angle, no supports needed.</p><p>35g of filament<br>3:30h Print<br>On Prusa Mini<br>0.20mm quality and 20% infill<br>If printing on PETG make sure you account for shrinkage.</p><p>&nbsp;</p><p><strong>Parts*</strong></p><p>5051 FAN - 2 x M3x20mm hex screw and 2 x M3 Hex nuts</p><p>5015 FAN Mount into X rail adapter mount - 2 x M3x16mm Hex Screw</p><p>X rail adapter mount&nbsp;- 2 x M3x12mm hex screws</p><p>X Axis Limit stop - 2 x M3x8mm hex screws</p><p>BLtouch &nbsp;- 4 x M3x8mm, 4x M3 Hex nuts</p><p>&nbsp;</p><p><strong>Installation</strong></p><ol><li>Screw in BMG extruder and Nema pancake motor with E3d v6</li><li>Screw in the BLtouch mount into the x rail bracket with the 2 M3x8mm hex screws and the 2 hex nuts in the back.</li><li>Screw BLtouch to mount using the 2xM3x8mm hex screws and the 2 hex nuts into the holes made for them in the mount.</li><li>Attach all hotend and screw 2 x M3x12mm hex screws on the right side, the left side if for the fan mount.</li><li>Attach to hex nuts to the holes in the fan mount and then screw 2 x M3x12mm hex screws into the left side holes in the adapter to secure the whole hotend setup on the x rail carriage.</li><li>Attach fan shroud to fan and then attach it to the fan mount, then screw in the 2 x M3x20mm hex screw into the 2 holes on the &nbsp;Fan they should then screw into the 2 M3 nuts you previously attached. This is meant to be a tight fit.</li><li>Get printing!</li></ol><p>&nbsp;</p>
