This model drops excess wind The concept is to use it quietly This mod may be a bit more difficult 5015-24v fan 5015-12v or 24v fan * Please note that the polarity of the fan electrodes may be reversed. DC-DC adjustable step-down power supply I need something that can be high pressure from 24v https://www.amazon.co.jp/dp/B010FJTHRC/ You can substitute 8 KΩ resistors with 0.5 W in parallel. I don't recommend parallel resistors because it can't be finely adjusted and it generates heat. This time, this base is used for power branching I expanded the mounting hole to M3 and used it https://www.aitendo.com/product/7244 Universal board 32x32 The holes for mounting the board are M3 and the spacing is 25 mm. fan.stl Filament cooling fan Uses 5015-24v or 12V fan M3-10mm 6 pieces 2 M3-20mm 1 M3 nut Is required Except for one board mounting location and fan mounting If you screw it in normally, you can fix it by self-forging. At this time, do not screw in the screws excessively. LED.stl I am using two 3mm resistors with a 3.3KΩ resistor in consideration of heat generation. I used hot bond for mounting The Y-shaped jig (jigu.stl) is as shown in the photo. After moving the hot end to the center Put it under the work fan nozzle A jig used to tighten screws and adjust the height. rleft.stl 5015-24v fan used Standard installation with loud noise 3010 Heatsink instead of cooling fan It is a part to move 5015 at low speed to mute M3-10mm 4 pieces M3-20mm 1 piece 1 M3 nut Is required btom.stl Prevents heat sink cooling fan wind from going to the hot block I used a PLA product for more than 10 hours and checked it, but it didn't burn. If possible, cut out a 0.3 mm thick aluminum plate into the same shape and use it. At a minimum, output in ABS or do not use left3010x2.stl Use instead of rleft.stl Use two 3010 fans that come with the main unit instead of the 5015 fan Since it is a standard installation 3010 fan with a loud noise, lower the voltage Even if it is moved at low speed, the sound deadening performance is inferior to that of 5015. M3-10mm 4 pieces M3-20mm 7 pieces 2 M3 nuts Is required 3010HalfFanGuard.stl Left3010x2.stl dedicated fan guard left4010.stl Use instead of rleft.stl Use 4010 fans instead of 5015 fans 4010 fan quieter than 3010, but lower the voltage Even if it is moved at low speed, the sound deadening performance is inferior to that of 5015.

Even if you lower the voltage and move it at low speed, the sound deadening performance is inferior to that of 5015. 20210105 left4010.stl 4010HalfFanGuard.stl 4010FanGuard.stl Use 4010 fans instead of the added 5015 fans. Lowering the voltage and moving it at a lower speed gives better results than two 3010 fans, but less muffling than the 5015. 20210109 Universal_board_dummy32x32.stp
