M5 Bolt-Pivot Fan-Out Sort Tray Tier
A four-cell parts tray (126 x 64 x 22 mm) with a 20 mm pivot boss bored to 5.5 mm. Stack several on one M5 bolt and they fan out sideways like a tackle-box tower, so the cells you aren't using swing back out of the way. Each boss is 24 mm tall, which leaves a 2 mm gap between tray tiers. The whole stack bolts through to a bench or under a shelf, and you set the swing friction by how tight you run the M5 nut.
Stacking Letter Tray Corner Post
This corner post lets you build a stacking letter tray from four printed corners and plywood or hardboard offcuts 3–6 mm thick. Each corner is 36 x 36 mm with a 50 mm tier pitch. The board rests on a 4 mm pad between two 3 mm walls and is held by one M3 bolt with a captive nut. A 4 mm pin on top fits the 4.5 mm socket in the corner above, so tiers stack without glue. For each board, trim each corner at 45° with 12 mm legs and cut it 6 mm smaller than the outside size you want: 222 x 285 mm gives an outside footprint of 228 x 291 mm, which fits US Letter.
Three-Tier Cooling Rack Corner Tower
This is a corner tower. Print four of them and you can stack three wire cooling racks of any rectangular size above the counter, with 48 mm between levels. Each tower is an L-shaped post 154 mm tall with 50 mm arms and 10 mm ledges supported on 45° gussets. A wide L-shaped foot keeps it steady, and the walls on the outer sides stop the racks from sliding off.
