This is a four piece enclosure that prints with no support material. The two breakout boards are secured with machine screws to the standoffs on bottom cover. The two speakers are mounted on the side of the enclosure and held in place with nuts. The Trellis PCB snaps onto a tray and placed on top of the enclosure - There's an inner lip that keeps the tray in place. The top and bottom covers are secured to the frame with machine screws.

CAD customization

The original solids are available in the 123DX file. You can modify the parts to fit your parts. If the tolerances are too tight or loose, you can easily adjust the parts by modifying the faces using 123D Design.

Filaments & Materials

The parts are optimized to print with PLA filament, but it should work with other thermal plastics. The parts can print with out any support material.

Slice settings

We recommend using the basic slice settings below. The parts are orientation to print 'as-is' so the parts should be centered on the build plate. For best quality, try printing part by part as opposed to a one print full set.

Finishing Parts

The enclosure frame tends to print with a bit of extra bits in the speaker cut outs. Remarkably, the bridge and standoffs print just fine without any support material.

You can remove the stringy bits using flush snips. Optionally smooth out the edges with a filing tool.
