A printed beam-flexure shaft coupler that joins a 5 mm stepper shaft (NEMA 17) to an 8 mm T8 leadscrew, with three 60°-indexed relief slots so it absorbs misalignment instead of binding the nut. 20 mm OD x 44 mm long, 5.3 mm and 8.6 mm bores, four M3 self-tapping grub screws (two per hub at 90°).
A ground stake with a tapered funnel socket that grips 12 oz cans, bottles and tapered party cups so drinks stay upright in sand, grass or dirt. 148 mm tall with four grip ribs at the rim for pushing it in by hand.
