Nâng cấp quạt Sovol SH01 (3010 blower)

This is an insert for the Sovol SH01 that works with 3010 blower fans directed through ducts directly at the source of heat for significantly better air distribution and improved heating. The result is faster heating, less hot spots in the dryer and if you pick the right fans - less noise!

BOM

2 x 3010 blower fans that operate at 12V (i.e. GDS time dual ball bearing - I did put a 47 Ohm 10W wire wound resistor on the positive line to reduce speed to 85% as my fans are overkill - noctua uses a similar 51 Ohm resistor in their fan silencer). I had these fans on hand and so you might want to try the Winsinn Dual Bearing (note: choose 12V dual bearing and not hydraulic!). You will need to connect all wires to the single original fan connector.

If you hate wiring… You could buy a 20cm 2 pin JST-XH extension and then a JST-XH splitter (i.e. this)

PRINTING

This model has been improved so the supports are integrated. I printed in ABS for heat resistance. If you print in ABS you will need to ensure your slicer accounts for ABS shrinkage as the model is designed without shrinkage incorporated (I used Califlower to tune for ABS shrinkage). My suggestion is: 20% infill, min 3 perimeters, min 4 top / bottom layers.

Unfortunately there are 12 errors detected in the original model. Your slicer will usually fix these, but it isn't necessary as it will print fine without them being corrected.

INSTALLATION

1. You will need need to gently remove supports from one of the screw hole bases (pictured here is the circular support on one side). There is another on the same end of the insert, but on the other side. 
2. You will also need to remove the bridging support highlighted at the bottom of the picture. The screws at the opposite end of the insert have a single layer for briding support that you should easily be able to screw through. The rest of the supports integrate into the model for significantly improved bridging.
3. Remove bearings/rollers from the original insert. Slide all bearings in (do not press from above). 
4. Do this while the insert is not in the box. For each roller, insert it in the middle and while supporting the outside, gently flex it until you can slide the roller down into the bearing. If you do this carefully there should be no breakages. Worst case is you can super glue broken bits back on, but this isn't ideal!
5. 3010 fans should easily angle in and press fit. I would suggest you first loosen the wire and thread through the insert. Mine are more than secure enough to not vibrate at all. You may need to use heat resistant tape to secure wiring. Wires should pass through and underneath the insert on the side opposite to the power.
6. You will need to break off the original fan mount. Getting this level to the other parts is sufficient.
7. You're now ready to connect the fans and screw down the insert using original screws. Be careful of the power inlet as well as the display pins. There is just enough clearance in mine.
8. I have left a section between blower fans for you to put desiccant sachets. Personally I put the colour change desiccant into reusuable tea bag filters. I think this is a much better solution compared to using a container. If you really want a container, then I would recommend using this instead in the middle of a filament roll.

BONUS TIP

If your SH01 doesn't let you set it for 48 hours, you should try the firmware flash. It requires some technical skill, but it has made life much easier for me. I put the details of how it works here. You may also want to look at the top post there to see all the mods the author did as there is some great options. I've created a collection of mods here on printables.
