3D model description

Think this is the proudest make for me on thingiverse ever.

This uses the most widely available cheap kitchen scale with a 5kg load cell in it. (as attached pic). If you have a different kitchen scale with similar spec, it's possible too, distance between the 2 screw of the load cell mount is 10mm, let me know if yours differ, I'll modify the file for you. FYI my load cell measures 75mm(L) x 12.5mm(W) x 12.5mm(H) in size.

*** NOTE ***
- Highly recommended to print the Thrust Stand at 100% infill
- I'm not a mechanical engineer, not sure what's the strength thrust this can take so do not go over 2kg thrust test
- Highly recommended to mount this permanently onto your table!
- If you can't, mount it on a thick kitchen chopping board, then clamp it onto the table
- I don't recommend printing the motor mount, make it out of 2mm alu plate. the file accepts 16mm, 19mm and 25mm format.

*** ALWAYS WEAR PROTECTIVE GEAR *** such as GOGGLE and long sleeve whenever you perform full throttle test! It's not funny. Anything can go wrong at those speed, unbalanced prop could wreck your stand, wires may be sucked to your prop(it happened).

If I'm free then maybe I'll make a nice enclosure like this. Or if DIY is hard for you, get this for USD93 only!

*** Assembly, ***
1. First print the stand, print it front facing down for strength, but upright is fine too
2. Remove the guts from your kitchen scale
3. De-solder the 4 wires of load cell from the board (take a pic of the board first!)
4. Slide the Two M4 screw into the stand, use a twizzer to put 4 washer over it(comes with it)
5. Tricky. Push the screw against the wall so it retains the washer there
6. Slot in the load cell 4 wires from top, carefully pull the wires through the bottom hole while you insert the load cell and align with the 2 screw hole
* PLS note the FORCE direction of the load cell, there should be a sticker on top
7. Screw it! Screw them...
8. Now load 3 M3 lock nut into those legs. Press fit easily
9. Now mount it on your preferred table or base such as chopping board
10. Mount your motor mount onto the load cell
11. Solder the load cell wires to your board and arrange the board, display, buttons to your creativity
