Two-bottle carrier generator
The opposite of a stacked, bolted build. It has one stadium-shaped tub with round pockets carved into it, and one handle that grows out of it: a stem tapering up from a flared foot into a rounded-triangle loop. The handle prints flat for strength along its length and drops into a hidden mortise, held by one M4 screw from underneath, so no hardware shows. The checks confirm the bottles lift and tip out past the loop, a full hand fits the grip, and the stem carries two full bottles swinging at 2 g against the material's allowable stress.
Ask for the sizes you want to tweak, e.g. “make the width adjustable”.

How to make it
- Measure your bottles' diameter and height and set their full weight.
- Print the tub upright and the handle flat on its back.
- Set an M4 heat-set insert in the tenon and screw the handle in from underneath.
Print tips
- PETG for a carrier that lives near a fridge or outdoors.
- The handle's strength runs along its layers, so keep it flat on the bed.
FAQ
How much can it carry?
The stem check uses your bottle weight at a 2 g swing and the selected material's allowable stress. That is a design estimate, so load-test your print before trusting it with glass.
