"Der Skorpion" - Fan Duct for Geeetech A10M and A20M dual colour printers

thingiverse

Update 29.12.2018: Version 1.1 of Skorpion has been updated with a thicker duct mount and a shortened duct outlet to increase distance from the heater block. The cooling system on my A10M and A20M was not fully convincing, so I designed this part with several key concepts in mind: 1. Replace two 30mm fans for the hotend with a single more silent 40x10 or 40x20 Fan. 2. Improve cooling with a radial 5015 Fan. 3. Allow better visibility of printing progress. 4. Make it customizable. 5. Achieve a good-looking design. The BLTouch has X and Y offsets as follows: X= -38 mm Y= +10 mm Please consider showing your appreciation by leaving a TIP if you like this project. Thanks in advance. You will need the following parts to complete the Skorpion modification: Extra Parts: 1x Axial 40x10 or 40x20 for the hotend 1x Radial 5015 for the Fan Duct / Part cooling fan (Ensure it is compatible with your A10M and A20M's 24V system) Printed Parts: 1x Part A+B(left+right mount) + Part C(duct) + Part D(FrontBit) + Part E(BLTouch optional) 1x Recommended Hotend PCB Mount: https://www.thingiverse.com/thing:3195894 Mounting Bits: 4xM3x12 for carriage 2 M3 screws for carriage 4xM3x16 for hotend (BLTouch + Fan Duct) 4xM3x16 for Hotend Fan (for 40x10 fan), and 4xM3x25(for 40x20 fan) Remember, all modifications you make to your printer are at your own risk. I disclaim responsibility for any damages that may result from this modification.
