I found that the Slim LM8UU Holder would snap if forced so I adapted it for side printing with super strong results.Download and print! They really are much stronger when you get the filaments along the bend. I added ramps to avoid unnecessary stringing.If slicing with skeinforge the standard one shell works fine and 30% infill is plenty! Plausible improvements: I might turn the nut trap so that no bridging is required if I can manage it in the modeler. Stay tuned.
