The rim. A ring 10 mm thick and 12 mm tall in PETG, so a dunk flexes and comes back, with twelve hooks underneath for a store net. At the back, a dovetail tongue slides down into the bracket on the board and locks - no screws, and a rim comes off in a second to swap for another size. The 7" and 8" rings print in one piece; the 9" is two pieces on pegs (a dab of glue makes it one).
The board. 7 mm PLA, printed face up: the name inlaid 1.2 mm into the face in its own colour, the border and the target box raised. The small board is one panel, 240 × 220 mm; the large is that panel with a 100 mm wing dovetailed onto each side, 440 × 250 mm, the wings in a second colour. Over the door: two printed hooks clip onto notches in the board's top edge and hang over a 35 or 45 mm door. On the wall: four countersunk holes for #8 screws.
From the store. A foam mini basketball - 4", 5" or 6" - and a mini-hoop net (twelve loops). Everything else is here.
