Ring Doorbell 3 & 4 Base

Ring Doorbell base, suitable for doorbell 3 or 4. The supplied 3mf model is set to 7 mm at the top and 18 mm at the bottom, resulting in a 4.9 degree tilt. Also included is my Fusion360 parametric model. The tilt angle and various other parameters can be changed. Simple edit the (fx) parameters and change the bottomDepth parameter to tilt the base as desired. Making bottomDepth the same as topDepth results in a flat, non-tilted, base. All the parameters are commented. This has been test printed on a Bambu X1C, using PETG filament, and it fits the Ring Doorbell, models 3 or 4, perfectly.
