Standing Desk Keypad Knee Bumper Bar
This U-shaped bar screws to the underside of a desk and hangs below a sit-stand desk's up/down keypad, so a knee or chair arm hits the bar before it can press the buttons and move the desk. It fits keypads up to 140 mm wide and 38 mm deep. The fingers still reach in from the front, and the 5.0 mm slotted holes in the two flanges take #8 or #10 wood screws with 8 mm of front-to-back adjustment. Overall size is 176 x 52 x 28 mm, and it prints flat so the knee load stays in the layer plane.
Standing Desk Handset Drop-Back Bracket Pair
A pair of Z-profile ears (joined by two snap-off tabs) that relocate a Flexispot, Uplift or similar sit-stand desk handset 40 mm below the desk underside and 17 or 43 mm further back, so knees and chair arms stop bumping it. Each ear is 110 x 40 x 36 mm with 4 mm walls: the desk plate takes two #8 wood screws through 4.6 mm holes on a diagonal, and the lower plate has two 4.5 x 24.6 mm slots for M4 bolts and nuts so the handset's own ear holes land on it at any spacing; the ears mount independently, so there is no handset model to match.
Office Chair Caster Parking Cup
This is an 80 mm dished floor cup that stops an office chair caster from rolling. It holds single or twin-wheel casters from 50 to 65 mm across and up to 26 mm wide in a 9 mm-deep bowl, so the chair stays put on hard floors at a desk or standing desk and the floor doesn't get scuffed. The body is 12 mm tall, the floor is 3 mm thick, and the rim is flat and sloped so a wheel rolls in with a nudge but won't roll out by itself.
Strap-On Desk Leg Cable Spine
A 119 x 60 x 21 mm snap-in cable raceway segment that straps to a desk or sit-stand leg and carries the cable bundle vertically: a 26 mm wide x 16 mm deep channel with lips narrowing the mouth to 18 mm so cables push in and stay put. Mounts with velcro or zip ties through two 18 x 4.4 mm wing slots (fits any leg profile) or two 4.5 mm screw holes (M4 / #8 wood screw, 4.2 mm shank), and each segment lap-joints into the next with a 9 mm tongue and 4 mm locating peg so you stack as many as the leg is tall.
