Based upon the Prusa Enclosure PTFE-tube Guide by Karza. My remix is a Dual Reverse PTFE-tube Guide. The guide is meant to provide an extra roll of filament in the ready for filament color and runout changes.
Please Like and Post your Makes. Much Appreciated!!
Use case is the inside ceiling (overhead) of a print enclosure (see pictures)
Filament: PETG (for the flexibility)
Infill: 30-50% (for the strength of the base and small amount of flex that occurs during a print)
