Redmond RHB-2983 blender repair kit (coupler, adapter)

The top part of the original adapter has turned into mess and melted and I had to guess its dimensions, so it's not a 100% copy of it, but it is 100% compatible :) As I see it in the photos from internet, the original adapter has 6 holes and thin bridges between them, maybe this is why it broke.

I made only 4 holes the way they make it in cheaper models. It increases the overall strength due to thicker bridges between holes. Actually, only 2 holes are enough, but it will be difficult to attach the stuff then, so 4 holes seem to be the best choice.

Low Tolerance version - more difficult to attach parts, but longer life due to little backlash. 

Adapter - I made it because I had to break the original one as I couldn't dismount it otherwise. Most likely you do not need to print it but if you do, print it without support, 0.2 mm layer height.

I'm not responsible for any harm or damage that this part can make to you and your blender. You should understand that this is a powerful blender with 1200 watt and 14600 rpm motor. 3D-printed parts are not the strongest ones. They can melt or break into pieces that will fly around and break everything on their way. To reduce the possibility of damage, use high melting temperature plastics and never heat the motor too much. I used PETG, but maybe ABS will be better here. Never use PLA for this model.

To increase reliability, use random seam position and slow speed when printing.

NOT FOR SALE, NOT FOR COMMERCIAL USE. The model is for home use only!
