DIY Shapeoko 3 Enclosure

Setting up a desktop CNC brings along two additional problems that need to be resolved – noise and dust. [Nick] upgraded from a Shapeoko2 to the Shapeoko3 and decided to build a fresh dust and noise proof enclosure for his CNC , and it turned out way better than he had anticipated.

When trying to build something like this, aluminium extrusions seem like the obvious choice for the structure. Instead, he opted for low-cost steel frame shelving units. The 3mm thick steel frame results in a nice rigid structure. The top and bottom were lined with 18mm thick MDF panels. For the two sides and back, he choose 60mm noise dampening polyurethane foam lined with 6mm MDF on both sides, and held together with spray adhesive and tight friction fit in the frame.

The frame was a tad shallower and caused the spindle of the Shapeoko3 to stick out the front. To take care of this, he installed an additional aluminium frame to increase the depth of the enclosure. This also gave him a nice front surface on which to mount the 10mm thick polycarbonate doors. The doors have magnetic latches to hold them close, and an intentional gap at the top allows air to enter inside the enclosure. A 3D printed outlet port was fixed to the side wall, where he can attach the vacuum hose for dust collection. The final step was to add a pair of industrial door handles and a bank of blue LED strip lights inside the enclosure for illumination.

It’s a simple build, but well executed and something that is essential to keep the shop clean and dampen noise.

Upgrading a hackerspace’s shelving


Shelving is probably one of the most underappreciated items in the shop. Think about it; would you rather have a place to store boxes, or a fancy new thickness planer, laser cutter, or pick and place machine. The folks over at the 23B hackerspace were growing tired of their disintegrating Ikea shelving unit and decided to make some shelves. They didn’t phone this one in, either: these shelves will be around far longer than you or I.

[Chris], the creator of these wonderfully useful pieces of metal, was inspired by a video featuring [Jamie Hyneman] of Mythbusters fame. An entire 80 foot section of M5 Industries, [Jamie]’s shop, is covered in shelving units constructed out of square steel tubing, put together in a way that’s easy to construct and able to handle amazing amounts of random stuff.

The new shelves for the 23B shop follow a similar design as the shelves over at M5, only a bit smaller in scale. It’s a wonderful beginner’s project for a welding and fabrication class, and more than sturdy enough to handle a few pull-ups.

Cable management for pull-out shelves

Cable management is a headache for all, and if unmitigated it becomes a playground for cats. [kws103] posted a project a while ago that takes care of the messy wires for electronics on pull out shelving. Channel bracket is used to house the cables and has been articulated in three places to facilitate the movement of the sliding shelf. For an added touch an outlet was built into the surface to make it easy to unplug and remove the components if necessary. The hinges for articulation use aluminum base plates and rely on rivets as a pivot point, something that might need improvement if pulling the shelf in and out is a common occurence. Add this to the Ikea based solution we looked at in August and your days of electronic rats nests may be coming to an end.
