My daughter wanted a simple Nintendo Joy-Con “bone” over the store bought one. She found this model on Thingiverse by manabun:

My first attempt to print failed at about 80% due to the raft coming loose.

My modification was very small: I cut 0.2mm off the curved surface and used a brim with 20mm width. Not much but the print finished without issue and all the controllers clicked into place with ease. My daughter later added the strap parts and they also clicked in nicely.

Now my wife wants one :)

Printed with Eryone tricolour PLA Black/Red/Gold

Note: I didn't run Dynamic Flow calibration on this filament nor Flow Calibration (problem with LiDAR and silky filaments). It was functional but I will definately do manual calibrations in the future to address the ghosting.
