Y-Belt Tensioner for Alunar I3 - Slight frame modification needed

thingiverse

Drilling a single hole in the acrylic frame is necessary. I initially attempted to avoid any modifications, but the required size for it ends up obstructing the heat bed. Required materials include: All three screws and their corresponding hex nuts from the original idler (M3). A bearing from the original idler, specifically an F623ZZ type. One extra screw of the same size as the others (M3). An additional hex bolt that matches the screw's specifications. One spring.
