Top Panel, 7.5-inch

A vented top panel for our 7.5-inch rack, generated to that frame’s own dimensions. Sits in the groove of the flat top rails and lets the heat out of the top of the stack.

Two depths, to match your rack. At 195 mm the lid is 190.5 x 195 mm and goes on the bed whole: one 3.0 mm plate, no seams, no hardware, and 75 cm³ of PETG against the 10-inch lid’s 172 — the single biggest saving in the narrow line. At 260 mm it is 190.5 x 260, too deep for the bed but not too wide, so it is cut once: two halves lapped along one seam and clamped by two M3 bolts.

In the box: the panel — and at 260 mm, the two M3 x 12 screws and nyloc nuts for its seam.

Choose: the depth of your rack, the vent pattern, hole size and density, and the border.
