Philips HR1372 new lid for big container (HR393501)

As Philips is designing original lids in a way, they get broken very fast and they are not repairable I was forced to either buy new one for 750 czk (half of the price of whole mixer at that time) or design my own …

I decided to go with second option and tried to design similar thing, little bit simplified so it's madable at home.

Lid fits similarly like original, mixer is also holding well and after several destroyed parts I think I managed to adjust design in a way it's also usable :) So far properly tested on lower speeds (1 & 2) with those I am confident it will work for longer period of time. I tested for short also on speed 4 and it still holded …

Previous designed got damaged on speed 5, I made some changes to prevent that, but didn't dare to test it yet as I am hearing too many complaints on “no mixer topic” at this moment … :D

Print instructions

Lid

I tried to print from PETG with snug supports from base plate, 50% filling, quality 0.2 layer height and it works fine. I think 30% filling could be also sufficient but didn't dare to try yet as print of lid takes long.

Coupler

Coupler is under heavy load and it must be printed with 100% filling otherwise it will fall apart when mixing. As material I used PETG, 0.2 quality layer height, snug supports.

It cannot be printed vertically as it will just snap on transition between layers. It also cannot be printed horizontally as print will be deformed (not only you wouldn't be able to fit parts into it, but also it could cause non-centric rotations and eventual damage). Best way I found so far was to print it under 35 degree angle with thicker radius touching bed and thinner radius being on supports.

Assembly

You will need:

• [Buy] Bearing 608ZZ - Or any other closed bearing (you will want to wash it and don't want oil getting into your food … :P) with dimensions:
  • Internal diameter: 8 mm
  • Outside diameter: 22 mm
  • Thickness: 7 mm (this might be slighly more, there is some space there)
     
• [Original container] Metal rod
• [Original container] Plastic “cup” for holding (can be easily disassembled just be pulling it …)

Start with assembling the coupler. Put bearing on top of coupler and only after that put rod inside (you will not be able to assembly in different order). Keep in mind, that rod will go easily at the beginning but eventually you will need to use a lot of force as it's made for tight fit - what worked for me was putting thick part of coupler on the table and then take pliers, put them on top of rod and push it down (up to 9 mm down) with weight of whole my body.

After this insert assembled coupler into lid from the top, push it into prepared slot for bearing and at last attach plastic “cup” for holding the knifes.

That's it :)
