This is a custom adapter to have a spool be a stand-alone unit, no case necessary It is designed for the ROBO R1+, and is meant to hold the spool in a center-balanced position.
I recommend using some rubber on the bottom to help stabilize it, or the spool holder will slide. I used some "rubber feet" from the bottom of an old laptop and they are working perfectly.
Recommend printing in MEDIUM quality or else it will take way to long.
Start the print in the morning is recommended on your day off.
High 29 Hours Estimate print time
Medium 12 Hours Estimate print time
Low 8 Hours Estimate print time
You can lower these by speeding print speed Etc.
