FAQ

Can this shelf hold my monitor?

We've tested 40lbs of weight between two legs spaced ~2ft apart with little to no bowing. Most monitors weigh ~15lbs. As long as you use quality wooden dowels and install the legs snugly, this desk shelf can hold your monitors.

If you have a heavy monitor, simply add a leg underneath the monitor for direct support.

Does this fit on smaller printers like the A1 Mini?

Yes! The small DeskShelf (5-dowel version) fits on the A1 Mini’s build plate.

All the add-ons also fit (larger accessories come in multi-part variations so they can print on smaller machines.)

How do I get the updated files?

You will get an email with a link to the updated files (check your spam/junk). However, you can always login to the shop and follow these steps to access your files.

How do I know what has been updated?

There is an update log here on the product listing (below), as well as in the STL pack in a .txt file.

Do I need the DeskRail STL Pack?

The DeskRail STL Pack is not required, it simply gives you access to a larger variety of mounts. The DeskRail STL pack includes StreamDeck Mounts, cable holders, MagSafe combo mounts, and more.

Great improvement of the setup

The Desk Shelf Pack is one of the greatest additions to my setup. Not only hides it the three monitor arm clamps, but also most of the cabeling. I also can use the space beneath the monitor now with little shelfs and such. The space under the monitor looked not well organized before. I totally love it.

Absolutely love my setup

Absolutely love my setup. I hate things on top of desk every where and with this setup everything has it's own place. It was so easy to make and put together.

Amazing desk upgrade!

Best Desk Shelf i found! The parts are easy to print and assemble, with lots of possibilities for different setups. It has made my desk look much cleaner and more organised, while also making it look and feel bigger with more usable space. Very happy with the final result. Highly recommended!

Absolute fantastic system

Absolute fantastic system and I am beyond amazed how many different versions and add-ons exist. It's also relatively easy to create your own additions, although having a parametric version of one or the other file would be amazing.

The Ultimate Desktop Riser with infinite customization

I was searching for the perfect desktop riser, and a friend pointed me to Work Space Hero and after looking at all the videos, his website and seeing just how many options there were it became a no brainer. When I first looked at this I was not thrilled with the wooden pine dowels but with some thinking and searching I was able to find Walnut dowels. With that and some wood polish I was able to make this solution exactly as I wanted it and have a premium look. I could not be happier and highly recommend this.

Full Customizable and Perfect for every need!

I watched these videos for weeks and then finally pulled the trigger and wish I had done it earlier! These system is so awesome and really makes my desk so much more useful. Ended up printing one for home and work because of how much I loved it. The possibilities are endless and I'm always added new stuff because more is always being added. It was definitely worth the purchase!

So many options and totally worth It!

When the modular desk shelves first caught my eye, I was hesitant to spend that much on an STL pack. I could always go look for various free options. I finally decided to get it and it has been totally worth it. Not just for what the STL pack included when I purchased it, but for the ongoing enhancements and additions. The quality of the prints is great and if something isn't that great, just wait, there are always improvements being made. I always enjoy seeing what's new and watching the videos.

Desk or more than desk

The Desk files are so simple yet flexible to use you can use them for all sorts of things. I already had a Desk shelf set up however it managed to solve a very simple problem of my partner‘s mirror not being high enough and not being tidy a few prints later in a particular colour and all of a sudden storage is much better. Only problem is now my daughter wants one.

Beautiful designs, almost prefect

I've bought a lot of Workspace Hero's STL packs and the designs are beautiful. The prints come out great every time, and the modular systems are well thought out. Being able to mix and match parts to build a setup that suits my desk is a big part of why I keep coming back.

When I first bought the desk shelf it was just dowels, spacers and a few basics. It has grown into a huge library of attachments, more than I can fit on my desk! The constant updates have kept it fresh, and it's great that he takes requests and works on them. I use so many of them: mounts for my Xeneon Edge, Steam Controller and Samsung wireless charger, plus the shelf inserts and extra STLs that fit random tech I had lying around. The DeskRail with the desk shelf is the best combination ever. The charger mounts were designed around specific models, so my generic Amazon one needed a bit more height to fit. The Samsung watch charger is still a work in progress for me. The shelf inserts are also tricky on my P1S, since face-down grooves don't print well, but that's down to my printer.

The only thing holding back the 5th star is the dowel size. Bunnings only stocks 19mm and 22mm($18 each) in Australia, and as you can see in my photo, the dowels span the whole shelf, so 22mm gets expensive fast. A 19mm version would be a big help for Australian builders, and I'd happily bump this up to 5 stars if one was added.

best desk system out there.

I really like this system. I have limited space and decided to go up with it. I have a printer on the other side so I couldn't go further to the right. I went up and it's stable even with the printer shaking the desk. I would go even higher if needed.

Great quality and variety of options.

I have been so impressed with the quality and quantity of available files. I was on the fence for a long time before finally moving forward. I absolutely love the customization available.
