This is ice scraper part I modeled to replace the broken one in my favorite design Snow and ice scraper and brush tool.
The term of this design is expired in 2014. So I just give a reference to the source of this excellent tool.
This work is in progress, since anyone else would require a handle for this part, but it is not modelled yet.
12/16/2016 - updated connection side sizes to better match the original one.
Layer 0.1 mm Nozzle 0.4 mm
ABS (or some similar hit resistant plastic) shall be used to survive against ice.
Bad warping is experienced during print, so any measures to prevent warping shall be used, so raft must be used. Also I added model with additional brim of 0.4mm height to improve adhesion.
Support is required on a small area near forward blade.
Use high temperature for ABS (no fan) to avoid delamination during use. I set 255 C, but I'm not sure how temperature sensor is calibrated.
Note higher temperature makes warping of ABS worse.
It took many hours to reproduce original design. There are still some simplifications and tricks to improve printability and durability of this part.
