Good Day, Today I bring to you a special test for anybody worried 
about retraction/ overhang/ and layer bonding (water tight) issues.
Please take into consideration it may only show issues on the XYZ 
distance it printed on, it is most effective when scaled at %150 
and z height adjusted as desired to check layer bonding issues. 
The final result should be a semi-hollow part that is waterproof
with no visible stringing inside and no blobs or bumbs on the 
outside. KEEP IN MIND THIS TEST NOT ONLY CHALLENGES YOUR PRINTER
SETTINGS BUT IT ALSO CHECKS THE FILAMENT IN ALL THESE CATEGORIES.
*This is also a calibration test for people printing the designs 
I have made and ensures one step closer to acheiving %100 solid
infill.
			PRINTER: TEVO TARANTULA (PRUSA I3 CLONE)

                        SUPPORT: %0 (NO SUPPORT)

                                 FOR WATERTIGHT RESULTS
