This is an epoxy bottle holder to hold partially used bottles (4.5 ounce size) upside down for faster use.

Each cavity has a ‘cup’ at the bottom to catch escaped resin in the event the bottle cap pops off - which happens sometimes when the temperature or barometric pressure change dramatically.

There are many similar bottle holders to be found on the internet so this one adds to your available choices.

Supports are not absolutely necessary but they will help to ensure that the print goes smoothly all the way to the top.

Sorry for the large STL file size. My CAD program exported it that way and can't make it smaller.

10%-20%

I used 10 perimeters and 20% infill. This keeps the printer from madly creating small infill patterns in the walls as they build up.

The floor (bottom) is only 2mm thick so there isn't much infill to do.
