Grabs

Printed parts that hold onto something you did not make — a motor face, a pail, a fan, a hose. The rule for every row: at most four numbers, each a tape across the thing.

25 of 29 rows are built. The rest are the catalogue, in order.

• G1-01NEMA 17 face mount

  31.0 mm square M3 pattern and a Ø22 pilot recess — the face every stepper-driven part bolts to

• G1-02A Raspberry Pi board

  A foot or cradle that holds the board by its outline. The hole pattern is adopted once the outline says which board. It is not a measurement.

• G1-03A square frame fan

  A well or clamp on the frame. Not a filter clip.

• G1-04A box fan and a furnace filter

  A clip that pins the filter to the fan. This is the four-tape rule.

• G1-05A laptop, closed

  A stand that holds it by the outside. Not a map of the underside.

• G1-06That laptop's power brick

  A cradle around the brick.

• G2-01A 5-gallon pail

  Printed parts that stand in the pail and clear its wall and lid. A water-scrubber's demister is the worked case.

• G2-02A 32 oz paint-mixing cup and its lid

  A pod on the bought lid, or a skirt over the rim. Not a snap designed from the bead.

• G2-03A metal paint can with a friction lid

  A hook on the rim. Speculative: no project names one.

• G2-04A bucket-lid gasket

  A ring that captures the gasket. Speculative.

• G2-05A Gamma Seal lid on that pail

  The stack has to clear a screw lid, which the snap-lid height does not.

• G2-06Gridfinity, one row

  One base or one bin. Not a catalogue. The scope test is only half met: the thing named is a standard, and the bins are usually printed.

• G2-07A rectangular storage tote

  A clip on the rim. Speculative. No project.

• G3-01A shop-vac hose cuff

  A printed port the cuff plugs into. Finding 17 changed which end is male.

• G3-02PVC pipe

  A socket or saddle on the outside.

• G3-03Copper water tube

  The same, a saddle on the outside.

• G3-04PEX tube

  A sleeve on the outside.

• G3-05A garden hose

  A sleeve on the hose body, or a jaw across the fitting flats.

• G3-06EMT conduit

  A saddle on the outside.

• G3-07Round duct or a rigid hose adapter

  A sleeve on whatever outside the tape says. The scrubber file shows 3 inch and 4 inch duct were assumed, then thrown out. Those sizes are not measurements.

• G4-01As-ripped 2x

  A jaw that accepts the ripped thickness. Not a second stud jig. Joinery already has that jig.

• G4-0223/32 ACX plywood

  A slot or edge clip sized to the sheet, not to the name. Speculative as a printed part: the loft file uses the sheet as structure. I did not find a printed grab there.

• G4-03S4S 1x board

  A jaw on thickness and width. Speculative.

• G4-04A thinner sheet, ½ inch class

  The same slot as G4-02, for a sheet that is not the 23/32. Speculative.

• G4-05A broom handle

  A clip or ferrule on the round.

• G4-06A hardwood dowel

  A bore or a clip on the round. Speculative.

• G4-07A tape-measure body

  A cradle around the case.

• G5-01Seed cell plate

  A plate whose rim cells each hold exactly one seed of a measured lot, for a plate meter; one keyed centre so every crop's plate is interchangeable (assemblies/seed-meter/BRIEF.md)

• G5-02Plate meter floor

  The plate's pocket, the drop port, a spring-dog cutoff riding the plate and a knocker over the port — the singulation
