Relay Module Enclosure for 5V 1 Channel Level Trigger Relay Module https://www.banggood.com/5V-1-Channel-Level-Trigger-Optocoupler-Relay-Module-For-Arduino-p-915614.html?rmmds=myorder&cur_warehouse=CN The relay module fits snugly inside the enclosure, which stays in place due to its tight design. Two holes on the bottom of the box enable easy removal when necessary. To close the box with a secure fit, consider the material used (PETG or PLA) and printer calibration. If the lid is too large or too small, try scaling it up or down by a few percent. Two ducts on the sides allow for securing cables in place using cable ties. A hole at the top provides easy access to LED indicators.
