2x Fibaro Double relay Switch box for heating

thingiverse

This is a customizable installation box designed specifically to control underfloor heating systems with 3-4 zones. Two double relay switches from Fibaro fit perfectly inside it. A small space is available for a Wago 221 connector, used to organize neutral wires and keep the box tidy: https://www.wago.com/221/us/. Three holes are located at the bottom of the box - one in the middle for connecting 230V power lines and two additional holes for inputting actuators that control zones. For example, you can use Danfoss TWA standard actuators: http://products.danfoss.com/productrange/list/heatingsolutions/floor-heating-hydronics/twa-standard-actuators/#/. A screw hole is located at the top of the box, but it's not necessary to use it since the top holds securely in place. I created this design for two relays because a single relay box already exists on Thingiverse. If you need to control more than 5 heating zones, consider using Heatit-Z-DIN-616: https://obchod.homesystem.sk/230v_svetlo/heatit-z-din-616/, or for up to 10 zones, use the Heatit-Z-Water: https://obchod.homesystem.sk/kurenie-a-chladenie/heatit-z-water/. This is my first design project, so please provide any feedback or advice in the comments.
