Monitor support

It's simple to adapt the design to include tripple monitors, I can provide tripple monitor plans on request. The reason this version does not include monitors is tactile feedback devices like buttkickers require a separate monitor stand because the vibration reduces the life of a monitor.

STEP 1 - Ordering

OSR will send you the digital plans normally within 24 hours. The digital plans are released using google drive, this process is 100% manual, so a little patience is sometimes required :-). It helps the process if you have a gmail account, but this is not essential.

OSR will send you the digital version of the plans and a shopping list to complete the project. Shopping list items include:

  • 40 or 15 Series Aluminum Extrusion 
  • Bolts, T-Nuts
  • 4 Hole and 2 Hole Inside Corner Brackets
  • Standard flat joining plates

Save money ordering aluminum extrusion

Aluminum T-slot extrusion is sold around the world, if you don't mind waiting you can save money ordering you standard 40 series bolts, t-nuts, L brackets, and flat plates from China. It typically cost too much to have the long lengths of extrusion shipped from China.

Metric 8mm bolts & 40 series t-nuts work with imperial 15 series, China does not typically sell imperial 15 series parts.
