I am a mechanical engineer, and serious about getting the quality products I need for flow toys that I print which get dropped and need to be very durable.
For the Makerbot 5th Gen printing with PLA plastic is just not a professional thermoplastic.
Figuring out how to print with ESun PETG was a process and involved designing a new filament spool holder but the result is amazing. The prints are so perfect and the properties of the plastic are better than ABS in some ways.
And it prints without a heated bed.
The PETG filament comes on a spool that does not fit into the Makerbot, you need a well designed filament roll holder not something generic on ebay sitting on roller bearings with no filament tube guide.
Also you need the right machine settings to print PETG and you probably do not want to go through all the trial and error I went through.
In PETG you can squeeze the locking tabs together 1,000s of times with no change, printed in PLA the first time I squeezed them together one side snapped off. PLA is to brittle and not strong.
Also I build a nice wood frame with stain and polyurethane.
My design is a similar design to what is on the machine sliding the Esun PETG spool over flexing plastic that locks the spool of filament in place in a rectangular wood frame and filament tube guide.
Possible other 3D printer models could use a stand alone filament roll holder like this.
Wondering if this would be a post worth pinning?
I would sell them for $99 plus $20 shipping.
