This is a selfmade doorbell with smart camera and fingerprint sensor. The camera is a Eufy Doorbell 2K and the Fingerprint sensor an Ekey S-Line. It consists of a printed case in the dimensions of four flush mounted outlets. Therefore the cutout in the wall can be made with a standard 68mm hole-drill. Sensor and doorbell are screwed to the case and a TPU cover is added which contains magnets, holding the front made of 1,5mm painted steel.
Printing:
1x file “Unterputzdose”, I printed in in PETG on my Prusa MK3S+ without support and 20% infill
1x “Namensschild”, printed in transparent PETG with 100% infill. You can either add your name to the 3D file and print it with a color change in a dark color or just put a sticker on top
1x “adapter deckplatte oberteil” and 1x “adapter deckplatte unterteil”, I printed it in black TPU with 30% infill so it sits flush with the steel plate but it can be printed in PETG as well.
Lasercutting (there are several online services offering this):
1x “Blechabdeckung.dxf” lasered from 1,5mm steel. It must be magnetic to hold, so if you choose stainless steel make sure it is a magnetic one. As it's used outside the steel must be painted so it doesn't rust.
Assembly:
- Print all the parts and order the steel plate and electric components
- Drill the holes in your wall, drill a hole in the case at the place where your cables are and mount the case with cement or expanding foam
- Connect the Doorbell with your existing doorbell wires as described in its manual
- Connect the Fingerprint sensor with it's cables going to the door controller. If you want to use WAGO 221-2411 connectors there are holders integrated in the case
- Screw both in their place
- Put the two pieces of the front plate together and glue in the magnets. Insert the name sign and screw it on with four screws and nuts.
- Add a piece of LED strip on top of the WAGO holder and connect it to the power of the fingerprint cables
- Screw on the frontplate
- Add the steel frontplate
