Ryobi RM300e/RM480e 48v Riding Mower Cupholder mount for Camway battery monitor

Many owners of Ryobi 48v electric riding mowers (RM300e, RM480e and RM480ex) have now upgraded their mower batteries from the sealed lead acid batteries that the mower shipped with to much more reliable 48v LiFePO batteries, which the built in battery monitor that came with the mower cannot provide an accurate reading for.  Because of this, it is common to install a third party battery monitor along with the Lithium batteries.  A popular option for this is the Camway battery monitor, which is slightly too big for the hole on the control panel where the built-in battery monitor is located, and requires widening of the hole to install it there.  

This print provides a nondestructive alternative method to install the battery monitor in the mower's cupholder, since the existing battery monitor is still useful to monitor the mower's used hours after the lithium battery upgrade.  There is a small existing hole in the bottom of the cupholder, and I have found that with some manipulation I was able to get the cable that runs between the battery monitor and the battery shunt through this opening without damaging it.  The battery monitor should be able to press fit fairly snugly into the 3d printed mount (the metal bracket is not required), which will then press fit into the cupholder and should be fairly secure.  A small hole in the side is provided which should allow a small screwdriver or pin to be inserted under the edge of the battery monitor for removal if needed.  

NOTE:  This design was tested using an RM480e; I believe the relevant plastic pieces on the RM300e should be the same and this should work with it.  The Ryobi 48v zero turn mowers have a different cupholder design, so I do not believe this would work with those.

Print notes:  Printed on a Prusa Mini+ using generic PLA at 0.2mm layer height with 15% infill.  I have found that the fit of the battery monitor in the mount is less snug if I use input shaping, so I would recommend printing without it for better print quality.  Have also printed on an Ender 3 S1 with similar results.
