CR10sPRO Bullseye with BLTouch
Description
I take no credit for this design as it is a remix of two designs joined together. I like the Bullseye fan duct for the Ender 3 but it is not available for the CR10sPRO. I found the design for the Petsfang frame for the 10sPRO made by CoolShooters https://www.thingiverse.com/thing:3426936 I took his design and the original designs from the Bullseye collection for the Micro Swiss and stock hotends and joined them together https://www.thingiverse.com/thing:2759439 I had to remake the BLTouch holder as the original design covered the hole in the carriage frame. To fit the BLTouch holder you will have to remove the carriage and hot glue or superglue a nut on to the reverse, doing this will allow a screw to be held in place for the BLTouch holder, see photo. By gluing it in place you can then remove the holder at a later date without the nut falling off. The ideal height for a BLTouch is 8.3mm from the bed to the bottom shoulder of the BLTouch, not the pin. I have included a simple height stl, depending on your printer tolerances you will have to measure this once printed to get it close to 8.3. Probe Offsets: x -48 y-10 Hardware required: M3 nuts x 5 two for the fan duct, two for BLTouch, one for the reverse of the carriage. M3x10mm x 2 to hold the frame to the carriage M3x12mm x 3 for the BLTouch holder M3x15mm x 2 to attach the duct M3 washers x 3 two for the duct one to attach the BLTouch holder. This stops the screw head going further than needed. I use a 4020 fan so I have used the following from 0mbr4: https://www.thingiverse.com/thing:4782085 Any of the Bullseye/Blockhead dual fan ducts should work with this design.
