The is the XL version of my Standard Keurig k-pod holder
found here https://makerworld.com/en/models/217858#profileId-236749
This version is a bit more weighty and can hold a total of 40 pods (16 on the back and 24 on the front)
its dimensions are 207.5 mm wide x 169.5 mm deep x 243 mm tall (roughly 8 inch x 6.5 inch x 9.5 inch)
No supports needed just print with the bottom flat on the bed (and buckle in, its a bit of a long print)
(ignore the logo on the top seen in the photos as this version has none)
