Four-Size Alligator Clip Boot Sprue
A snap-off sprue of four tapered slip-on insulating boots to replace the cracked rubber boots on alligator and crocodile clip test leads. Jaw-end openings are 7x5, 10x7, 14x10 and 18x12 mm, the boots are 22, 28, 36 and 44 mm long, and the wire holes are 3.0, 3.6, 4.5 and 5.5 mm. Each boot has a finger-stop flange, so you can re-boot your clip leads without buying a whole new set. Measure your clip's handle and pick the boot just over that size. Print in TPU if you want a softer boot.
8–25 mm Hole Transfer Punch Sleeve Set
A snap-apart set of six flanged centring sleeves for 8, 10, 12, 16, 20 and 25 mm drilled holes. Each sleeve has a true-centre 3.4 mm bore for a 3 mm pin, an M3 screw or a 3 mm drill bit. Drop one into a hole in the first part, clamp it to the mating part and punch or pilot-drill through it, and the hole lands exactly on centre. The shank is 6 mm long so it sits flush in stock 6 mm or thicker. The shanks are 0.15 mm under nominal for a slip fit, and the flange is 6 mm wider than the hole, so each sleeve is easy to identify.
Pilaster Shelf Clip Four-Width Sprue
Snap-off sprue of 16 hook-style shelf clips for slotted steel pilaster standards in bookcases, closets and store shelving, four clips each in 3.4, 4.0, 4.6 and 5.2 mm prong widths so you can match a slot the shops no longer stock (pick the column 0.2 to 0.3 mm under your measured slot width). Each clip is a single top hook (1.8 mm thick, 1.5 mm crook for steel up to 1.4 mm, needs a slot at least 6 mm long and 3.5 mm of cavity behind the strip) over a 16 mm bearing pad, with a 14 mm gusseted ledge and 2 mm front lip; it works on any slot pitch, and in PETG expect roughly 5 kg per clip, about a quarter of the steel originals.
Split Ball Joint Hemisphere Set
This set holds every ball and spacer for the 'SG90 Mini Delta Pick-and-Place Robot' kit on one 87 × 87 mm sprue tree: 24 hemispheres, each 12 mm dia × 6 mm tall with a 3.4 mm M3 bore, and 12 spacers, 7 × 5.25 mm. Six hemispheres have a 6.2 mm counterbore for an M3x40 SHCS head and six have a 5.7 mm hex pocket for the M3 nut. Snap them off the sprue and they make the six ball pairs that seat in the 12.4 mm cups of the link rods.
