I did not like the original print when I used auto orient and printed it without supports.

This model eliminates the need for using supports and makes it easier to print. Uses common m3x6mm screws to install.

Assembly Instructions:

• Just lay it flat and print without supports
• Cut the 4mmptfe tube to length to fit the inside
• Enlarge the ends of the PTFE with a Philips or allen key for easier screwing
• Use two m3x6mm (m3x4mm if works) screws to install the tube

Printing Instructions:

• Material: ABS or at least PETG for high temp and sturdiness
• Infill: 100%
• Supports: No
• Rafts: No
• Brim: No
