Two single-column stands from the bench guide. The column jig (Order 1) is two planks, five 3D-printed parts and the parts you ordered. For the weight tests (Order 1) you bolt a printed tower onto it and stack the weights straight above the nut. The encoder tab (Order 1, bench step L) shows the magnet, the printed mount and tray and the TBMA732 under the motor's rear shaft; the wiring tab places the Nucleo, the BOB, the 30 V rail, the fan and the supply around the jig with every wire of the bench guide's table. The printed stand tab shows the same column on four printed parts and no wood (bench guide step E2); its heights start at the table. Drag to rotate, scroll or pinch to zoom, right-drag to pan. Every height is in millimetres from the top of the base board; the screw axis is the centre line. The Pololu bracket sits on a 2 mm shim (its motor axis is 28.4 mm from the leg, the jig needs 30.25 mm); measure the coupler hub and the KFL08 bolts too.
