A bit chunky, but wanted a handle for my Yeti Rambler.

This one printed from PLA, the top and base are designed to be printed with the lugs flat to the bed.

I used a brim when printing the top part as it's a snug fit, so any warping could mean it won't fit (I found this out the hard way). The bottom is slightly loose, but I figured it doesn't matter too much, I'm not planning on swinging this around, it's just to make it easier to carry from the kitchen to my desk.

Internal diameter of the “hoops” that hold the mug are 77mm.

Comes in four pieces that screw together, thanks to the embossing on the bottom of the mug I put it together as follows:

1. Screw handle into base
2. Slide top bit over sippin end
3. Screw top to handle with the screw

I've added a 2nd version of the top part with a notch in the inner diameter to allow the embossed logo to pass through, this means I can now slide my mug into the handle without having to dismantle the top section (for washing, etc). I also added a chamfer to the tab to match the lower section.
