Old Version ESun Refilament Spool Converter (dessicant slot optional, no glue required, screw-in)

Main Considerations:
 - NO CENTER SPOOL HOLE, must be supported at bottom only
 - You must cut the ESun spool in half to use this
 - For plastic, not cardboard ESun spools
 - Check if refilament cardboard core is around 92~93mm inner diameter (known working refilament in pictures)


Recommended printing settings:
0.2mm layer height (larger layer heights should be ok due to large tolerances, but may not generate the brim-like structure for the Spool to Roll ring)
Many overhangs in screws and nuts and many bridges, so fan should be on for them

Models may require reorientation (largest diameter part of all models placed on the bed)

Spool screw requires supports; in support painting, just use fill tool of modern slicers to pick the protruding ring when looking from under the model (the other recessed ring will thus be bridged)

"Final Spool to Roll Ring" has a specific assembly method: the large notch should line up with the ridge on one of the halves of the spool you have cut so the ridge does not offset the ring ('large notch' is opposite the brim looking side) -> is a tight fit, some force will be necessary

I recommend placing the desiccant side on the side with the hole that shows filament remaining

Optional Desiccant slot: (for sachets and possibly beads)
"Dessicant screw" requires "Dessicant Screw Modifier Cylinder" to be lined up at same position for use as a modifier (i.e. the cylinder should pass through the marked-on-model circle).
The "Dessicant Screw Modifier Cylinder" should be set to change the model at the modifer region to NO top or bottom walls and to the infill + infill density of your choice (should be gyroid or any 2D infill in order to allow air to pass through; note that a high infill density may allow use of individual silica gel beads, but they may fall out if the size is misjudged so err on side of higher density).

note that the desiccant slot is smaller than expected, but can still fit at least one large dessicant sachets or multiple small ones
