Eurorack module stand 3U – holds a module upright for testing, repair and photos, 4 to 42 HP

Flat base with a slot for the bottom edge of the front panel: the removed module stands upright on the desk, the back stays free.

Fits: Eurorack 3U modules up to 4, 12, 24 or 42 HP (panel dimensions after the Doepfer A-100 construction details); no electronics. Not affiliated with Doepfer or Intellijel; the names only identify the dimension source and the format, and the part is not an accessory by any manufacturer. No logos and no lettering on the parts.

Please note: nothing of this design has been printed yet, and it has not been tested on a case. The dimensions come from the sources named under “Dimensions”. Print the free fit gauge (in our “Magmacode” profile) first.

A removed module usually lies on its knobs on the desk or falls back onto its circuit board. The stand holds it upright by the bottom edge of the front panel: for measuring and repairs, for photos or simply until it goes back into the case. The jaws only grip the lowest 6 mm, the strip that sits on the rail in the case.

• Slot for 2 mm front panels: 2.4 mm wide (2.0 mm + 0.4 mm clearance), 6 mm deep, chamfered at the top. PCB front panels (1.6 mm) lean slightly; printed panels thicker than 2.4 mm do not fit.

• Touches no electronics: according to Intellijel, circuit boards end at 110 mm height at most, which leaves just over 9 mm free at the bottom. The jaws are 6 mm high, the feet 3 mm flat.

• Free at the back: only two flat side feet, 25 mm to the front and 70 mm to the back; ribbon and patch cables stay free.

• Printed flat, no supports, the way it stands on the desk.

Variants: Four width classes, length of the stand: up to 4 HP 44 mm, up to 12 HP 64.6 mm, up to 24 HP 125.6 mm, up to 42 HP 217 mm. The slot is open at both ends; a wider module still stands but overhangs at the sides. Print time, filament and dimensions in the shop refer to the class up to 12 HP.

Dimensions: Dimensions taken from Doepfer A-100, Construction Details and Intellijel 1U Technical Specifications (3U PCB height); our part has not been tested on a case yet. Front panel 2.0 mm thick and 128.5 mm tall, widths from the Doepfer table (4 HP 20.0 mm, 12 HP 60.6 mm, 42 HP 213.0 mm); circuit board height 110 mm at most (Intellijel). The 24 HP width is not in the table and follows Doepfer's rule; the clearance in the slot is our choice. If the slot is too tight or too loose, the tolerance comb of the fit gauge shows how your printer prints slots. Print the free fit gauge (in our “Magmacode” profile) first: it shows whether hole pattern, screws and your printer work together.

Load: For a single Eurorack module, guide value 0.5 kg, not a tested load rating; not for cases or other devices.

Material: PLA is enough, PETG works too: the part only carries one module. Do not leave it in the sun or a hot car, PLA softens from about 55 °C.

Variants (all included)

• up to 4 HP

• up to 12 HP

• up to 24 HP

• up to 42 HP

Print settings

• Material: PLA (or PETG). Do not leave it in the sun or a hot car: PLA softens from about 55 °C.

• Layer height 0.2 mm, 2 walls, 15 % infill, no supports.

• Orientation: Flat, slot at the top, no supports.

• Print time approx. 24 min and about 8 g (default variant up to 12 HP: complete part; other variants differ).

Assembly

1. Switch the case off and remove the module.

2. The short feet point to the front. Stand the module in the slot from above by the bottom edge of its front panel, knobs to the front.

Safety

For a single Eurorack module, guide value 0.5 kg, not a tested load rating; not for cases or other devices. The part has no electronics and carries no current. Switch the case off before fitting or removing panels. Hold the module with your other hand when plugging or pulling cables, otherwise it tips over together with the stand.

Fit

Slot 2.4 mm for 2 mm panels; too tight → check the tolerance comb of the fit gauge.

FAQ

Which size do I need? The class whose HP number is at least the width of your module. Narrow modules also stand in a larger stand; wide modules stand in a smaller one but overhang at the sides. Does it hold 1U tiles or panels of another thickness? Any front panel 1.6 to 2.4 mm thick stands in the slot, 1U tiles too. A 1.6 mm panel leans a little; a strip of tape on the back of its bottom edge makes up for it. Have you printed the part and tested it on a case? Not yet. The dimensions come from the sources named; the part has not been printed or tested on a case yet. That is why you should print the free fit gauge first. Which material? PLA is enough, PETG works too: the part only carries one module. Do not leave it in the sun or a hot car, PLA softens from about 55 °C. Does the part carry current? The part has no electronics and carries no current. We deliberately do not offer bus boards, power supplies or device adapters with electronics.

How it's made

Parametric CAD (build123d, Python), exact solids. The CAD code was written with an AI assistant and checked by us; no AI-generated meshes or images. Renders are made from the CAD in Blender and show the part in simple staged scenes (placeholder case without brand, wooden table); they are not photos.
