Triple Noctua 4020 Satsana remix with BL Touch for Aquila

prusaprinters

<p>This design is for the Voxelab Aqulia (including X2). It's a remix of a remix that gives good clearance for the BL Touch. I like Noctua fans so wanted to fit three!</p><p>The two filament fans are wired in series for 24V operation.</p><p>The heatsink fan is wired in series with 2x 120 ohm 1W resistors. (two in series to spilt the power drop - allowing us to use 1W resistors with good margin).</p><p>This solution means you don't need to rewire the main board or use a buck converter and it should be more reliable.</p><p>If you choose to use a different 12v fan for the heatsink then adjust the resistors to match the value as the fan. Fan resistance = 12/Fan_current. Use two 1W resistors in series to add up to the approximate value. E.g if the fan current is 90mA, the fan resistance = 12/0.09 = 130 ohms. Use two 68 ohm resistors.</p><p>The two ducts should be printed upside down, use supports to fill the box.<br>I glued the ducts to the side of the main piece.</p><p>I've cleaned up the Satsana model a lot, removing a lot of surface artifacts. The design only gives marginal improvement to overhangs but print surface quality is better on all sides.</p><p>It's a lot quieter too which is the biggest reason for this upgrade..</p>
