Corny keg scale (Plaato) - from Thingiverse

Not as much of a remix as it is a re-design. I do thank @misperry for his insightful video and STLs he shared here.

I redesigned this scale to fit the build plate of the Ender 3 Pro. The finished diameter will be 207mm (8 3/16") - just smaller than a keg.

I borrowed @patrick3345 50kg loadcell brackets, took the mounting holes off, and modified the retention ring a bit so they would clamp the loadcell down and leave a wire chase.

The screw bosses can be tapped with a 4mx0.7 tap or a coarse thread screw (no tapping).

I put the screw bosses next to the loadcell mounts to leave plenty of room for the circuit boards.

I also modified misperry's feet a bit as when I printed them on the Ender, the post was a hair high and the flair at the bottom of the post prevented it from seating all the way in the hole. Probably a machine thing, but I chamfered the post and hole opening, and tightened the tolerance for a snug fit - no glue needed.

I omitted a hole for the power port and LED lights as these can vary a great deal. Shouldn't be too hard to drill a hole.

EDIT: (5/7/23) Edited bottom screw holes to accept M4-.07 x 12mm screws
EDIT: (5/8/23) Added a short version of the feet to reduce the overall height of the scale
EDIT: (7/12/23) Added a wider version of the top and bottom for pinlock kegs. The finished diameter is 8 11/16". All other parts will fit. You may need to edit your slicer settings to a 235x235 build plate as this version is just over 220mm.
EDIT: (7/30/23)Fixed the top(s) so slicers won't try to fill in the center hole or the loadcell bottoms. They should slice perfectly now.
EDIT: (8/15/23) Forgot to fix the bottoms for the same reason as the tops. Should be good now.
EDIT: (8/17/23) Fixed foot hole alignment on pinlock top & bottom.
EDIT: (2/13/2024) Added SKP files so you can edit in Sketchup as you see fit. Mind you...some of these files may be unfinished, unrealized, or incomplete. These are the files I used to create the final product.
EDIT: (6/1/24) Added 100-sided ball lock version for those that want the outer walls to be a smoother version of the scale.
