RTIC 30oz Tumbler Handle
This will fit the RTIC 30oz tumbler. I found out the hard way that the other model on thingiverse for the 30oz yeti, doens't fit the rtic. So I created this file from scratch, also made the handle longer for my hand (I'm a big dude). I made this file very 3d-printer friendly, no supports needed or platform adhesion. I printed it with 3 shells, and 50% infill. It feels extremely sturdy perhaps was overkill.
Version 2 makes the model a little bit more ergonomic.
UPDATE Version 3:
The second version had problems with overhang. This version fixes that problem, nothing over a 45 degree overhang, which should be doable by most printers. This is the model I would recommend. It is the blue handle in the pictures.
NOTE:
This model is for right handed people, left handed people out there need to mirror this model on the x axis in their slicer software and they will be all set.
