Trash Bag Roll Holder for Cabinet Door

Keep the trash bag roll right where you need it: on the inside of the cabinet door under the sink. Two small brackets (left + right) hold the roll in open cradles. Pull a bag over the front lip and tear it off at the perforation.

- Any roll width: two separate brackets, so you space them to match your roll (no rod, no core needed).

- Two sizes: R40 for rolls up to 78 mm diameter (most 20–60 L bags), R50 for rolls up to 98 mm (120 L bags).

- Side cheeks stop the roll from sliding sideways. The rounded front lip lets the bag slide out smoothly.

- Mounting: 2 screws per bracket (3.5–4 mm, 12–15 mm long for 16–18 mm doors), countersunk, holes above the cradle so the screwdriver reaches them. Strong double-sided tape also works.

- Solid, compact profile (12 mm wide). Screws are not included.

Print settings

- Orientation: as supplied (lying on the side cheek). No supports, no brim.

- 0.20 mm layer, 3 walls, 15% infill. PLA or PETG.

- Time on A1, PLA, 0.20 mm (pair = left + right on one plate): R40 – 50 min / 25.8 g; R50 – 1 h 01 min / 35.7 g.

Tip: mount the brackets first, then drop in the roll so the bag comes off the top towards you and hangs over the front lip. Designed from scratch by bezbajzlu.
