Prusa Enclosure Heatbed Cable Cover

<p>After an extended use of the Prusa i3 MK3 60 degree heatbed cable cover, my thermistor cable weared out and I had to replace it. I loved the original heatbed cover and wanted to stick with it after the replacement.</p> <p>I had to use the enclosure after installing the original heatbed cable cover, therefore I designed a flanged cable cover to be mounted on a cutout in the acrylic sheets. The holes for the screws and nuts are for standard M4 scews and M4 nuts. The flanged design allows for a tolerance in the form of the cutout so you dont have to be very precise when cutting out the acrylic sheet.</p> <p>This way I was able to use the original heatbed cable cover for the enclosure and it works great!</p> <p>If you have any feedback or comments please feel free to share.</p> <h3>Print instructions</h3><p><h3><b>Print settings</b></h3></p> <p><ol></ol></p> <p><li><b>Material:</b> PETG, please do not use PLA since it can deform because of the increasing temperature inside the enclosure.</li></p> <p><li><b>Infill:</b> Gyroid %20 should suffice</li></p> <p><li><b>Layer Height:</b> 0.20mm</li></p> <p><li><b>Supports: </b> Middle part of the print is too aggresive to print with bridges, I recommend using support enforcerers for that bulging middle section. </li><br/> &lt;/ol&gt;</p> <p><h3><b>Preparation &amp; Installation</b></h3><br/> <b> Step 1 </b><br/><br/> Determine the location where the heatbed cable buckles and mark it down using a pen.<br/> <br/><b> Step 2 </b><br/><br/> Mark down a 92mm in height, 46mm in width rectangle with a center point of your previous mark.<br/> <br/><b> Step 3 </b><br/><br/> Cut out a rectangular (92mm(h) x 46mm(w)) hole in the acrylic sheet at the back side of the printer using the marks in step 2. I used a laser cutter but you can use any tools that could work with acrylic, precision in dimensions is not critical because of the flanged design.<br/> <br/><b> Step 4 </b><br/><br/> Place the cover into the hole, with an orientation shown in the pictures and mark down the hole locations using a pen.<br/> <br/><b> Step 5 </b><br/><br/> Drill out the holes that you marked down using a 5mm drill bit. Using a sharp drill bit is critical at this point, since acrylic is a pre-stressed material using a dull drill bit may cause cracks.<br/> <br/><b> Step 6 </b><br/><br/> Place 4 M4 nuts in the designated places in the cover and place the cover on the acrylic sheet.<br/> <br/><b> Step 7 </b><br/><br/> Screw in the M4 screws and you are done!</p>
