Basic stand created to hold a pushbutton board, LCD display, and an Arduino Nano board for my A450 Press. Only the .stl is published - the Fusion 360 file is a mess (was using Fusion for the first time when creating the stand).
Printed face down in PLA with a 0.20 layer height and a 0.4 nozzle.
The Arduino Nano is programmed to count the number of finished rounds in the tray (or made during a session), and the number of primers (starting from 100) left in the primer tube.
Uses the following models:

Please let me know if you find this useful for your own purposes, or has given you some ideas for your own reloading press or Arduino project.
The author marked this model as their own original creation.
