I’d used the same little 40-roll filament rack for years, and I finally outgrew it. So instead of buying a bigger one, I built a wall-mounted rack that holds about 126 rolls — 14 across and 9 rows tall — for roughly $27 in wood. No printed parts, no fancy hardware, and it goes together in an afternoon. A ton of you asked for the plans after the video, so here they are, free.
The quick specs
- Holds: ~126 rolls (~14 per row × 9 rows)
- Cost: ~$27 in wood
- Build time: one afternoon
- Printed parts: none — it’s all lumber
- Row spacing: 10½" pitch (a clean 9" gap), with the back rail raised 2" so every spool tilts back into the cradle and can’t roll off the front
What you need
| Material | What it’s for |
|---|---|
| 2 × (2×6 × 8 ft) | Vertical side posts — cut to your ceiling height. The 5½" depth runs wall→room and forms the cradle. |
| 1×2 × 8 ft strips | Horizontal rails. Each row uses two (a front + a back); 9 rows = 18 rails. |
| 2" wood screws (~36) | One at each end of every rail, plus a few into wall studs. These are what actually hold it. |
| Brad nails or wood glue | Optional — just to hold each rail steady until the screws go in. |
Tools: circular or miter saw, drill + pilot bit, tape measure, pencil, stud finder. A rotary tool with a cutoff wheel makes the awkward cuts (the bottom rail by the floor, the end trims) a lot easier.
How to build it
- Cut both 2×6 posts down to your ceiling height. They stand vertically; the 5½"-deep face runs from the wall out into the room.
- Lay a post flat. Starting near the base on the front edge, mark the first rail, then mark up every 10½" (bottom-of-rail to bottom-of-rail). That leaves a clean 9" gap between rails — 9 marks, 9 rows.
- For each row, mount the back rail about 2" higher than its front rail. That tilts every spool back toward the wall so it seats in the cradle and can’t roll off the front.
- Run the rails full length, overhanging the posts — don’t pre-cut them to width. Hold each in place with a brad nail or dab of glue if you like (optional).
- Drill pilot holes, then drive one screw at each end of every rail. The pilot holes keep the 1×2 ends from splitting.
- Trim the overhang: line up one end flush, then cut the excess off the other end — front and back — for a clean rectangle at whatever width your posts sit.
- Stand it against the wall and screw the back into a stud so a full load can’t tip it. Then load up — drop a spool into each cradle, ~14 per row.

Not into building?
Totally fair. The pre-made rack I used for years before this is right here on Amazon — it’s the one I outgrew, but it’s a solid place to start if you just want something off the shelf.
