Hello again,
R36S is a fantastic device for the price. it does however get very uncomfortable with the vertical layout and finger gymnastics required to reach shoulder buttons and analogue sticks.

This grip aims to provide a bit more ergonomics and a comfortable "grip" of R36S device.

print vertically as shown on the photos.

I have not designed this, the original and full credit goes to @jpjoao_nasc and his RG353V grip.

I just used tinker CAD to add a bigger hole at the bottom. have to say the original design mold is fantastic both from comfort point of view and ease of print point of view.

the final product is a tad (0.2 mm) bigger than the R36S so the device feels a little loose.

you either want to print it like 99.5% or just use painters tape for a tight grip just like i have done.

my printer settings are;

anycubic pro max 2, PLA + at 207 degree Celsius in 0.2mm layer height with supports

please let me know if there is better way to do supports as the bottom looks a bit ugly.

all the best.
