Tower Frame End Plate
Part of the '2020 Gridfinity Drawer Tower' kit: a 198.5 x 141 x 6 mm frame plate that holds four 2020 aluminium extrusion posts. It uses the same part at the base and, flipped, as the top cap. Each post sits in a 20.4 mm U-socket, 20 mm deep and open on the front or back so the drawer fronts can pass. Each socket takes three M5x8 screws into drop-in T-nuts through 5.5 mm holes. Four 4.6 mm holes take #8 wood screws, and the 39.25 mm side bars act as the top drawer's hold-down.
Delta Servo Top Plate
A 5 mm thick tri-lobe top plate for the 'SG90 Mini Delta Pick-and-Place Robot' kit, about 161 × 162 mm. Three 32 mm column pads at radius 75 mm have 20.6 mm × 1.5 mm locating recesses on the underside and 3.4 mm holes for M3x10 SHCS into the columns' heat-set inserts. Each of the three servo lobes has a pair of 3.4 mm slots, each giving ±4 mm of radial travel, so the SG90 cradles can be adjusted on M3x10 screws. The lobes also have an arm-swing notch, and the hub has a 30 mm wiring hole with a zip-tie slot pair.
Flapper Spine Frame Plate
This is the 84 x 108 x 5 mm backbone of the 'SG90 Scotch-Yoke Flapping Wing Rig' kit. It has a 12.6 x 24.5 mm through-pocket for an SG90 servo, with solid tab lands so you can drill pilots through your own servo's ears. It also has a 56.8 mm wide slide channel for the yoke slider, with four M3 heat-set bores (4.0 x 6 mm) for the retainer strips, and two 16 mm shoulder posts, each with a gusseted M4 heat-set bore (5.5 x 10 mm), that the wing rockers pivot on. It prints flat on its back face. The bottom 15 mm tongue has two 3.4 mm M3 clearance holes 60 mm apart for the display stand, and lightening windows keep it under 80 cm³.
2020 Mid-Span Diagonal Knee Brace
A 45° diagonal brace that bolts onto the inner faces of two 2020 extrusions meeting at a right angle. Each foot sits 60–112 mm out from the corner, so the corner itself stays clear. Each foot takes two M5 bolts (5.5 mm clearance holes, 20 mm apart) into T-nuts, and a 5.6 mm key rib drops into the 6 mm slot to stop the foot twisting. Braced this way, a gantry or rover frame is triangulated and resists racking under motor torque much better than a plain corner gusset. The part is 112 x 112 x 20 mm, printed flat so the bracing load runs along the layers.
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.
