Building a monorocket inspired eurorack case

I thought of that afterwards, sorry.

Looks a lot like custom stands, unlikely you can buy exactly such off-the-shelf. But a screw socket to attach it to the case should be no problem to find. Then it should be possible to take any metal rod and use a thread cutter, and afterwards bend it slightly. The case looks promising, good luck!

Stupid idea maybe but I bet there are Meccano parts that would work.

And here it is <3

Applying the tolex was much harder than I thought. However after some time we have got the knack. :slight_smile: The hardest part are the edges on the front. You need to be really carefully so that they join nicely. The first edge we tried is a bit ugly (top right), however we can may fix it later with some additional tolex.

We used SG5 tolex glue, which gave use an hour of applying the tolex. A lot of time!

The depth for modules isn’t 7 cm like planned, it’s 6,6. I forgot to subtract the depth for rails, etc…

The spring reverb and power supply are fitting awesomely well. There is maybe 0,2-0,3cm headroom between rails and the parts. :slight_smile:

I’m super happy about the 7 cm I chose. The whole case is half as thick as monorocket cases and I can still insert deep modules + spring reverb (type 9, the longest) and power supply. It’s also lighter. Less wood, less weight.

The power supply is working great. Monorocket is using two (one for 12+ and one for -12), I’m using one that provides 12+, -12 and 5. It’s awesome and it saves 500 Gramm weight :slight_smile:

The case + inserted modules weights 15 kg. A lot… The heaviest part is the wood (estimated 9-11kg…). I could chose 9mm plywood, but 12mm gives it a bit more stability. - apropos stability: It’s stable like hell. :slight_smile:

I still need to add some legs to it. The ones I bought are too small.

I’m very proud about this case. It’s awesome <3

There are some missing modules. Braids, Pressure Points, CP3 Mixer, Optomix (I only have two real vcas right now o0), R-54, Plague Bearer and Turing Machine :slight_smile: I will get them soon.

Absolutely lovely!


Damn, spot on! I see you went with the MN color. Couldn’t find that pink huh :slight_smile:

Wow. Really great job.

Dude - your case looks top notch! It’s inspiring me to DIY a case just like it. I’m probably going to go 6U x 84hp though. (I know, I know…) I have my mean well, I have some Frank busboards, now I just need the case… and the time to get this project done!

Looks fantastic!

Thanks for your comments :slight_smile:

@cold_fashioned Calculate at least 2-3 days of working time. It took longer than I thought. :slight_smile:

Infographic of depth for modules:

120hp x 30mm because of Power supply and spring reverb
106hp x 50mm because of Bus Board
152hp x 65mm because nothing underneath :slight_smile:

Ossom! or “päris hea” like I like to say in estonian.

@flocked: Awesome job with the tolex! Thanks for sharing this.

THIS just makes me want to build my own case so much more. Its beautiful! I’m thinking of 2x104HP, going to ask Stefan for the rails.

@janniz: Thanks :slight_smile:

6u x104hp is great :slight_smile: I think also about building a smaller case for some more portability. But more likely 7u x104hp so that I can add the upcoming make noise 1u cv bus. It gives you line in amplifier, multiples and stereo/headphone out.

Btw: I just realized that the displays of yarns and braids are causing noise inside the spring reverbs. Even when they are placed at the bottom row. Strangely Yarns display causes much more noise than braids… um :confused: :smiley:

woah! impressive design man! how do you like the 126 hp rails? I’m planning to buoild a DIY case myself but I can’t decide if go 104 or 126 hp.

126 hp is moar

I think that eventually you will use that extra space

the case looks really great! One question: Do you think the Meanwell is sufficient for 128hp and 9U? Any problems so far? The 5V part should be more than enough, but on the -12V the Meanwell seems a bit lacking for such a large case.
And did you wire the Meanwell straight to the busboard? Some people here have also suggested to use some capacitors between the power supply and the busboard.

No caps needed and in doubt use 2 Meanwells for separate BusBoards (please don’t wire them together !)

Don’t wire two busboards to one Meanwell, or don’t wire two Meanwells to each other (and to one or more busboards)?

Don’t connect the output of two Meanwells together I presume. If one fails then the other would be toast as well.
