Because the cooling on my A10M and A20M was not quite convincing, I designed this part with following concepts in my mind: More silent 40x10 or 40x20 Fan itead of the two 30mm fa for the hotend Better cooling with a radial 5015 Fan To see better whats printing Customisable The BLTouch has following X and Y offsets: X= -43 mm Y= 30,7mm Check also the space so far you need some What you'll need: Extra parts: 1x Axial 40x10 or 40x20 (recommended) for the hotend 1x Radial 5015 for the Fan Duct / Part cooling fan Printed Parts: -Base -Front -PCF -BLT Mount (optional) 1x recommended Hotend PCB Mount: Mounting bits: 4xM2x12 for carriage M3 Screws 4x 25mm 2x 10mm 3x 15mm(for BLT) 2x - 4x 15 /25m for the Fan 2x M3 nuts for the Partcoolingfan I highly recommend a silicon sock on the hotend, otherwise, you will get min Temp Erro over 30% of the Partcoolingfan Special Thanks belongs to Akos Wornerth that gave me a lot of input and hints he made also some kind of fanduct with the fan infront Edit: 26.12.2018 Fixed a small Slicer issue in the Fanduct Modell, its now Beta 4 , thanks for the Feedback!
