Print instructions for "fullbody" roll adapters with open faces

So you want to print the proposed open-faced roll adapters? Here is how: 

1. Rightclick on your part and add a cylinder modifier. Change its X and Y size to the diameter of the the roll adapter you want to print minus 2x your perimeter thickness. You can find that value in “Print settings/Layers and Perimeters” in the lower part of the "Vertical shells" dialog (it says recommended thin wall thickness).
   
   In my case I want to print a 54 mm roll adapter with 2 perimeters. The recommended thin wall thickness for 2 perimeters is given as 0.86 mm so I substract:
   
   54 mm - 2 x 0.86 mm = 50.28 mm
   
   This means my modifier has to be 50.28 mm wide and deep.
    
2. As your Z size put value bigger than 21.5 mm (that's the total height of the roll adapter) and then center your modifier, in my case that would be 90/90/11 in the "Position" dialog.
    
3. Then rightclick on your modifier and choose the option "Layers and Perimeters". There, set your bottom and top solid layers to 0.
    
4. Slice your part and have a look at what it will look like. Maybe play around with the infill pattern and density. In my case I went with the honeycomb pattern at 15% infill

Modified designs:

• "roll_holder_10mm_sunk_nuts" replaces the original "rollholder-10mm-ex.stl" and features sunk nuts, which makes assembly easier. It's a tight fit, you'll probably have to press the nuts in with some pliers.
• "roll_washer_sunk_screws" replaces the original "rollholderwasher-ex.stl" and allows for M3 flat head screws to be flush with the washer. And if you use 10 mm long screws they will fit perfectly inside and outside.
• "roll_adapter_XXmm.stl" combines the original "Cap-Roll-Adapter-D10-ex.stl" and "Roll-Adapter-XXmmHole-ex.stl" in one part so no assembly is needed after print.
  • You can also choose to print the "roll_adapter_XXmm_fullbody.stl", in that case I would recommend you to skip the bottom and top solid layers and choose a cool infill pattern to have a cool rotating part to look at ;) To do that, you can follow the instructions below!

Original designs:

• "spacer_clip-on.stl" is a new part, that can be clipped on the aluminium tube to a) prevent the roll adapters from slipping off all the time and b) help center the filament roll, if it is narrower as in my case. You can simply reduce or enhance the Z-dimension of the part in your slicer (while not changing X and Y) to fit your spool width.
