I made this hand held attachment to power my Lido grinder. It turns on automatically when you place it on the grinder and holds itself in place. Then turns off when removed. It charges through USB or wirelessly with any Qi compatible charger.

Parts List:
1. 3D print the three parts found in this google drive (~$35 shipped) [ Ссылка ]
a. If you don’t have a 3D Printer, head over to r/3Dprintmything where there are plenty of folks willing to print your thing at a reasonable price
b. Point them to the drive above and specify the following: Material = PETG, Part 1 in-fill = 50%, Part 2 in-fill = 50%, Part 3 in-fill = 100% and a color of your choosing.
2. Tacklife SDP50DC or SDP51DC Cordless Rechargeable Screwdriver ($20-$30). These used to be available on Amazon but recently disappeared from that marketplace for some reason. Find many on eBay here: [ Ссылка ]
3. M4 Stainless Steel Washer ($1) Look for them at your local hardware store, but you can get them in bulk here: [ Ссылка ]
4. M4-0.7 x 8mm screw ($2) Look for them at your local hardware store, but you can get them in bulk here: [ Ссылка ] This fastener is 2.5mm hex drive which is conveniently the same as all of the other fasteners on your Lido and the hex driver it came with.
5. Micro Limit Switch ($7) You may be able to find a compatible switch at your local electronics store, but I recommend you buy the exact one for which this product was designed. The only problem is, you have to buy them in quantities of ten: [ Ссылка ] A word of caution: Make sure you use one with a plastic “roller” on the end of the arm. The one I used for my first prototype was just metal and it scratched the paint on the top of the grinder.
6. 1/4 Inch Drive x 9/16 Inch 12-Point Socket ($5) [ Ссылка ]
7. 3 ft Right Angle Micro USB Cable ($7): [ Ссылка ]
8. Qi Standard Wireless Charger Receiver Module ($8): [ Ссылка ]
