Extended Hopper and Slow Feeder Insert for Timemore Sculptor 78/ 78s
Instructions: Just put the extended hopper over the existing hopper and the slow feeder insert into the hopper. The original cover can be place on top of the hopper. No modifications required.
Extended Hopper: You may need to print with support for the ledge that rest on top of the original hopper. There are some protrusions on top of the hopper to better secure the cover but you can always slice it off using the slicing software if you prefer not to have it. There is no protrusion at the back so you can still slide the cover back halfway.
Slow Feeder: This is designed as an insert that you can put into the extended hopper when you want to do slow feeding. The hole is designed to be at the front. It's a simple design where you pour the beans on top of the slow feeder and push the beans into the hole as fast (or slow) as you want. To remove the insert and use it for normal grinding, just hook out the insert using the hole. The insert is designed to have a tight fit but just sand the sides if you prefer something that is less tight fitting.
I just started learning CAD, so it may not have the best design but it works for me and hopefully for you as well.
