Tray is printed in two sections. .3mf file has everything, stl's are separated out for you already.
To put them together put the pegs in the holes. Print with supports for the holes/pegs (organic). There is 0.1 mm tolerance on the pegs so it should be easy to assemble. Use some super glue in the peg holes and along the seam to hold it together.
Print in PETG so that it won't melt when you spill some boiling water. PLA will probably be fine for splashes since boiling water will rapidly cool (unless you spill alot!).
There are blocks in the model, delete these if they aren't required. Some scales use the feet and not the body to determine the weight. If your scales use the body and fit the hole, you can just push it in. If your scales use the feet to determine weight (like mine), having it on a raised surface allows the scales to actually work.
The author marked this model as their own original creation.
