Katadyn Combi stand

This is an adapter for Katadyn Combi that lets you stand the water filter upright when attaching an outlet hose to the bottom. Print Settings Printer: FlashForge Creator Pro (2016) Rafts: No Supports: No Resolution: 0.1mm Infill: 25% Notes: Threads need to be relatively smooth, so print at high resolution or smooth them out after printing. Running the cooling fan might help. The quality of printed threads can be affected by your slicer software. For example, Slic3r (as I had it set up) added little bumps between the threads. Other slicers didn't have this issue. Note that Katadyn filter itself is made of ABS (at least the part this object screws into). I don't think thread wear should be a problem, but you may want to avoid filaments that are abrasive or extremely hard. How It Was Designed Designed in FreeCAD 0.16 I had to play around with threading to get it to work without breaking model's faces. Aside from avoiding overlapping faces, one of the biggest non-obvious steps was cutting ends of swept helix with primitive cubes before joining threaded cylinder to rest of object. Many attempts to taper thread or move start of threading down cylinder broke the model. After a lot of trial-and-error, I found current model to be good enough - not as polished as I would've liked but functional nonetheless. STL was fixed in Netfabb before uploading to Thingiverse.
