toothpaste reel-robust

I used one of these for 2 years before it was beginning to fail, so I designed a new toothpaste reel with thicker, stronger, and bigger components, made to be printed in optimal positions for strength. after 36 months I have seen very little evidence of creep.  

print in the positions shown in the prusaslicer screenshot.

the length of the slot in the body is 70mm/2.7in long.

pla+/petg/any CF filament.

0.3mm of tolerance

3-4 shells

25%or more infill

temp-235c for PLA

print the shaft/handle on the flat section located on its side, it should be flat, printing vertically will compromise strength.

--update, fixed import model unit size so it's not microscopic--
