Opentotum "Aeolos" Milling Head

thingiverse

DEPRECATED. See: https://www.thingiverse.com/thing:2429919 21/04/2017 - A reworked version has been uploaded, fixing some issues. It should work, but I can not test it, as I no longer have a working hybrid head. If you try this design and it works, thanks. Aelos is a case for the FABtotum hybrid head PCB. You must own such a hybrid head (or maybe alternatively a V2 Milling head). Check if it will work with your model, as I do not own one. It's possible to buy one second-hand, as many people don't mill and print quality is not hybrid heads strongest point. Post in the forum. If you remove the extruder from the hybrid head: https://github.com/Opentotum/Opentotum/wiki/hybrid-head-v1-extruder-removal, now you have some space for dust extraction. This head is designed to accommodate a 24 mm diameter pipe. My best match is a washing machine dirty water pipe like this one: http://www.hornbach.de/shop/Ablaufschlauch-100-cm/7309601/artikel.html Both end connectors are not the same size. Only one fits in "Aeolos". For my very reduced trials so far, the other end fits a Dyson v6 absolute (without any v6 accessory mounted). I plan to design a different solution. Why is this a thing in progress? Well, my flex cable has degraded further and now I do not have 24 V in the carriage anymore. I simply cannot mill and I cannot test it with the milling motor on. Print Settings: Printer: FABtotum Print Settings: Supports: Yes Notes: I printed mine in ABS in 0.3 mm layers. You need supports. If you can use a double extruder with a soluble support this is a good chance to use it. This design is extremely sensible to warping. If it warps 1 mm in the edges you won't be able to fit the PCB without reworking the PCB area. For this reason, it may make a lot of sense to print it in PLA (I have run out of PLA and I am testing "Zeus" with ABS, so I had non-technical reasons to do it in ABS). Post-Printing: Cleaning support If you can use a double extruder with a soluble support this is a good chance to use it. Cleaning this part out of support takes around 3 hours and a lot of patience. This is because I wanted just one part enclosing the duct and maximize the section for the airflow. How I Designed This: FreeCAD v0.17 Fully designed with FreeCAD v0.17. Full source attached. Take a recent version as it uses B-splines in the Sketcher.
