Description
A literal translation of standard 2-inch Schedule 40 PVC pipe, coiled tightly to fit perfectly within a 6-inch round by 8-inch high volume. The bend radius on this is mathematically impossible for physical schedule 40 without buckling, but it prints exactly to spec.

Sleeve is a plain, precise hollow cylinder sized in inches: a straight-through bore and a clean outer wall, ready to use as a spacer, bushing or standoff. Dimensions Outer diameter: 0.385" (9.78 mm) Inner diameter: 0.26" (6.60 mm) Length: 0.75" (19.05 mm) Wall thickness: about 0.0625" (1.59 mm) Print notes Print standing on end, no supports needed. Bore may print slightly tight; ream or scale up a touch if fit matters.

A hex tube, 4 cm tall, for when a round spacer or standoff spins or rolls where a flat-sided one would hold still. The 2.5 mm bore runs the full length so a rod, wire or screw passes straight through. Key dimensions Height: 40 mm Width: 5.15 mm point to point Center bore: 2.5 mm diameter, through the full length Printing Print standing upright, no supports needed. Walls are thin at the hex flats, so use at least 2 perimeters and a small nozzle if possible.
A flat 28.5 × 40 × 3 mm plate with an 11 × 11 mm raised square pad, 0.5 mm thick, centered in X and set 2 mm from the Y- edge. Remix hooks Pad thickness (0.5 mm): a multiple of your layer height keeps the pad clean. 0.5 mm is about 2 or 3 layers. Pad offset (2 mm from the Y- edge): move it along Y to centre it or push it to the other edge. Plate length (40 mm): the pad is 11 mm, so any length above roughly 15 mm still holds it. Pairs with: a label, a sticker, or a second pad in a different colour for a multi-colour swap.
Flat 45 × 42 × 2 mm ground plate with two side tabs on the front 45 mm edge and two small blocks on the back edge. Overall width across the tabs is 50.4 mm. Plate: 45 × 42 × 2 mm, sharp edges Side tabs: 1.4 mm thick, flush with the underside, 50.4 mm overall span Back blocks: 1.5 mm wide, 1 mm thick, 1.5 mm protrusion, 5 mm from each side edge Print flat, no supports needed
A servo can't turn a valve knob without a socket that grips it, and a loose fit slips under torque. This cylindrical socket slides onto the knob from the bottom and keeps the top face flat and closed for a future servo horn. Key numbers Body: 30 mm diameter, 14 mm tall, chamfered edges Cavity depth: 10 mm, opening only on the bottom face Opening at the bottom: 2.6 mm × 16.7 mm, widening to 4.5 mm × 16.7 mm at the inner end Clearance: 0.15 mm per side, with rounded corners and slightly bowed long walls Top wall: 4 mm solid, with no screw or mounting holes Printing: open face down on the bed, no supports needed; the wall slope is about 5° from vertical Cavity size, taper, corner radius and clearance are all adjustable parameters
A plain square block measuring 5 mm by 5 mm by 1 mm, flat on the bed and ready to print. Remix hooks Footprint: 5 x 5 mm is the starting value. Change it to make a tile, spacer or shim. Thickness: 1 mm is about five layers at 0.2 mm. Raise it for a sturdier piece. Edges: Add a small chamfer or rounding for a softer look. Keep it under 0.5 mm at this size. Pairs with: Use it as a test cube for tolerance checks, or as a base for a hole, text or a peg.
