Thanks for the feedback and pictures @nieldefize. hehe still some fine-tuning to do there!
Make a protection cap without any screws or bolts that may come off
Usually we have a different kind of input (welded, without bolts/nuts) this one was made last minute for safety reasons for you guys in Delft. Didn’t suspect the bolts to fall out thought. Probably a nut with rubber inside prevents this.
Add a button with which the shredder can turn the other way
Make it easy to remove the strainer so that the plastic (or unwanted parts) can be removed.
This was already our ‘easy to remove’ version. But can always be easier! Do Let me know if you have suggestions
Make some sort of cooling system so that the plastics won’t melt an get stuck.
Not sure if cooling would be the most effective way, perhaps a simple change in the blades setup (not a spiral) prevents the plastic from moving into on area,heating up and sticking together. Will do some test.
See you on Friday!
