Parametric Drip Tray

This is an upgrade to my previous plant pot drip tray model to make it fully parameterized. In essence, this drip tray is a disc with five concentric ridges and channels cut between them to let water collect and evaporate evenly. almost all dimensions of the model are customizable, except for the bottom thickness and the number of concentric ridges. If you'd like to customize the model to your liking see the below list of parameters that can be tweaked:overall_diameterthis one's self explanatory - the overall width of the circular drip trayinner ridge widththe width in mm of the four internal ridgesouter ridge widththe width in mm of the outermost lip of the drip trayridge spacingthe width in mm of the space between each of the five concentric ridgeschannel_widththe width in mm of the channels cut through each internal ridgeoverall heightthe overall height of the model, including the constant 2.5mm bottom thickness, so use this to change the depth of the ridgesinner_ridge_offse
