42HP Complete Eurorack Case

prusaprinters

This is a 42HP 3U Eurorack case. The structure is interior so it may interfere with some modules at the left and right ends of the rack. But the interior structure allows units to be combined in a row. Units can also be stacked. The rail “nuts” are 3D printed and are self-tapping with M3 bolts*. Rack units can be bolted together or to other hardware or boxes using M4 bolts or M4 threaded rods. Holes are self-tapping.Module depth at the middle: 41mm.Module depth at the left and right edges: 26mm.Side edge width at back: 5mm.Module depth at 5mm from left and right edges: 38mm.Overall dimensions: height: 132mm; depth: 51mm; width: 42HP = 8.4 in = 213mm.PLA material used (with 15% infill, .15mm layers): 153g, 51.3m*Note: If over time you find that the rail “nut” threads have become stripped and are not holding the bolts well, it is easy to apply a small amount of “gel” or “thick” grade cyanoacrylate glue (“CA”  super glue) into the holes with a toothpick. Allow the glue to harden before re-inserting the bolts. Also do not overtighten the screws with a screwdriver. Hand tight is enough for rail bolts. Updated to v.15 with reduced overhang of rail for easier printing.Also available: 3D printed 42HP and 34HP rails
