MPMD Effector Part Cooling Vents and Casing

<b><u>Updates:</b></u> <u>20/12/2020</u> I've revamped this project and created a better unit with dual 4010 duct fans: https://www.thingiverse.com/thing:4692277 <u>22/02/2020</u> I've uploaded a new side fan holder that fits 4010 side duct fans. This design was created to address the issue of arms catching on the outside edges when printing to the largest diameter of the bed with the original back-mounted design. The rods in this version clear when the effector is pushed out to its limits, so I recommend testing for clearances before printing, as your print may have a bit more filament extruded or be slightly off-scale. You can trim anything that might not clear. I've wired my heatsink cooling fan directly to the power supply and it works great with the part cooling vent system. <b><u>Components:</b></u> 1. **Heat Sink Casing** This component is used in conjunction with a triple or double vent base and requires positioning the nozzle so that it protrudes about 1-2mm beyond the base of the vents. 2. **Front Cooling Vents** I've designed three different front cooling vents to cater to various part cooling needs: * The standard style directs air away from the nozzle in cases where you may not want any part cooling. * The second design channels excess heat from the heatsink fan as part of the part cooling vent and is used with the triple vent base. * The third design directs air towards the back area of the nozzle and can be used with 2 or 3 air pump hoses. 3. **Part Cooling Base Vents** I've designed three different part cooling base vents to cater to various part cooling needs: * A double vent that supplies air to the back area of the nozzle. * A triple vent that supplies air to the back and front of the nozzle, which can be fed using 3 or 2 air pump hoses respectively. * An updated version of the triple vent that sits close to the heat block and touches my silicone sock. 4. **Rear Manifolds** These are holders for small side duct fans (3010) if you decide not to use an air pump: * A single fan unit that can be used with a 30x10 side duct fan. * A double fan unit that can be used with 2 - 30x10 side duct fans. * Another double fan unit that combines the features of the previous two and uses 2 fans mounted at angles. <b><u>Printing:</b></u> I print all items with their bottoms to the bed, except for the Heat Sink Casing which I lie on its back. I set supports to touch the bed only and often use a large brim to ensure they don't get knocked as they print closer to the top. <b><u>Warning:</b></u> Due to tight tolerances, be sure to test fit and scale when necessary (depending on your printer's dimensional accuracy). For all parts, especially the Front Cooling Vent and Rear Manifold, test fit before assembling on the effector. I also place all bolts and fit nuts prior to assembly as well to ensure that everything fits well.
