Slanted Box and Top Panel with Rotary Encoder cover

thingiverse

A box with a slanted 45 degree cut at the opening for housing components used in an Arduino Timer - has two small holes at the top face sides for sticking two 5V passive buzzers from inside, a rounded switch hole on the same face between them. It also has four diagonally placed holes so that one can screw on a top panel for the box. It includes a hole in the back face for USB port connection and a thin platform right above it to hot-glue a TP-4056 PCB module. A top panel with base cut to 45 degrees which has holes to fit in a 4 digit 7 segment display and a rotary encoder - has borders to prevent the display from falling out, and a rotary hole threaded at 0.8 pitch. It also has holes to be slid onto a box and screwed. A cover which fits on top of the rotary grove encoder (360 degree) for comfortable rotation of the encoder - overall diameter is 15 mm, with a 10.5 mm deep cut, rounded shaft and 16 grooves cut on the curved surface.
