Laser is from @SainSmartofficial and works really well. Fast, accurate and clean cuts. Check it out here: https://www.sainsmart.com/products/l8...
Drawer slides are from @BlumInc . Undermount soft close, our favorite. Easy to instal also.
This is part of our modular cubic workbench project. We have a lot of other videos showing how we build it and all the features. Check it out if you get a chance.
