BEAR X=Axis Extruder for Mosquito Hot End

thingiverse

After a day of too much beer and not enough time, I figured I'd tackle a problem that may or may not have existed! I previously modified a Slice Engineering Mosquito hot end for my CR-10S, and I'm still in the process of building a Bear full Upgrade MK3. I saw where Chris Warkocki had expressed a desire for a Mosquito for his latest build, and like everything else I do, I thought it should be fairly easy. What you see here is the result of about twenty hours of redesigning the excellent work done by the Bear designer, Grégoire Saunier. As a tribute to his work and the open source nature of his designs, I'm sharing my re-mix for all to use. **PLEASE BE ADVISED THIS IS A WORK IN PROGRESS** I still need a few parts to complete this project and get my Bear printing, and I'll update this page as work progresses. Preliminary prints of the housings show a good fit, and parts for this are easily sourced from Slice Engineering for the Mosquito Hot End; https://www.sliceengineering.com/shop/the-mosquito-hotend Also available from Printed Solid is the E3d style adapter; https://www.printedsolid.com/products/groove-mount-coupling-with-tapped-holes-for-slice-engineering-mosquito-hotend (They also carry the Mosquitos for a one stop shop). Since the Mosquito sits 3mm lower than the E3d adapter, there's a spacer STL for moving the Mosquito down to the same level as the stock E3dV6. Additional hardware needed should only be longer 2.5mm socket head screws to hold the adapter and spacer together, 2.5mmx12mm should be good. Please note that either the stock Mosquito cooling fan or the stock Prusa fan can be used (I recommend the Mosquito fan, it just works!). Now for those of you wondering, yes, you will need to update Marlin to disable the fan speed sensor since the Mosquito fan has no speed sensor. I'll post that when I get to that point in the build. **5-8-19** Updated license to "GPL" and added Fusion360 files. **ALSO PLEASE SEE THE UPDATED HOUSING FILES-added more space for the Mosquito Fan- THE SPACER IS NOW 2MM THICK- this is needed when using the E3d style adapter from Printed Solid** Additionally, if you're using a 25mm fan on the Mosquito, you'll need a 5V 3pin fan. If you're using an MK3 Einsy Rambo main board, one suitable part # is EC2510M05CA, and no need to disable fan speed sensor in firmware. **5-9-19** Modified extruder body, recessed the nut further to avoid interference with Mosquito. Also modified the X-carriage so a 3x10mm can be used for the lower extruder mount without interfering with the Mosquito. I added a picture to show before mod. **5-12-19** Uploaded latest Fusion360 file with modded x-carriage
