FAQ

Why does the price keep changing?


The DeskShelf STL Pack is constantly updated with new models and add-ons. As the pack grows, its value increases. All updates are free for existing customers, so the earlier you buy, the more value you get!

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 using the email you purchased with, navigate to your order history, and download the latest STL pack.

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.
