This does NOT include the resin-printed L/R buttons for the mintyPi v3.5! Those are optional and separate, and can be found here: https://shop.sudomod.com/collections/mintypi-v3/products/mintypi-v3-5-resin-l-r-buttons
These silicone, injection-molded buttons are custom-made just for mintyPi v3/3.5 and mintyPi Lite! They are listed separately from the printed parts so that you can easily pick whatever color combination you want.
They are longer than your typical L/R button as some people prefer that, but they are very easy to trim down to whatever size you would like, and a 3d-printed guide for snipping the end off is even included.
