2020 Extrusion Bolt-On Three-Cell Parts Bin
A 120 x 55 mm three-cell scoop bin that bolts to the side of any 2020 aluminium extrusion workbench, test rig or robot frame using two M5 bolts and T-nuts (5.5 mm clearance holes, 80 mm apart). A 5.6 mm locating rib drops into the 6 mm T-slot so the bin stays level. The sloped 45 mm-to-30 mm rim and 45° scoop ramps let you sweep screws out with a fingertip. It keeps small fasteners on the frame, right where you're working, instead of loose on the bench.
2020 Extrusion Offcut Rack With T-Nut Trough
This bench rack has eight 20.9 mm square sockets that hold 2020 aluminium extrusion offcuts upright. Next to the sockets is a 94 x 20 mm open trough for M5 T-nuts and screws. Each socket has a 10 mm push-out hole in the floor, and the rack screws to a bench through two M4 clearance holes. Overall size is 100 x 75 x 30 mm.
2020 Extrusion In-Line Splice Channel
A 100 mm U-channel splice that joins two lengths of 2020 extrusion end to end. It has a 20.4 mm cradle and 12 M5 clearance holes (5.5 mm) on the centre line of the floor and both side walls, for M5x10 bolts into T-nuts. A sight slot at mid-length lets you check the two beam ends are butted before you tighten. Use it to extend rover or gantry frames from short stock lengths, or to build frames that come apart for transport.
