Webbing and hook-and-loop tape sewing guide, 10-50 mm

Holds hook-and-loop tape square on a strip of webbing while you sew, so you stop chasing it across the machine bed. The webbing sits in a channel with a low side wall, and a small post keeps the tape lined up. Set your own webbing and tape widths to match.

Parts

  • guide · PETG · Standing upright on the feed end (the funnel end), with the tapered nose at the top. The lips over the webbing are part of every printed layer, so it needs no supports.

    At the defaults it is 55 x 70 x 7.5 mm: about 12 g and 26 minutes at 2 walls / 15% infill. PETG because the strips slide over it the whole time you sew.

Notes
Stand it on the feed end, as set in the 3MF. At 2 walls / 15% infill it takes about 12 g and 26 minutes at the default 70 mm length. Brim: 5 mm for lengths up to 80 mm, 8 mm from 81 to 100 mm; the engine checks that this keeps height to base depth (brim included) at or under 5:1. On a bed-slinger li

Hardware

  • 4 × Neodymium disc magnet 10 x 3 mm · For the default 'magnets 10x3' mount. Guides shorter than 55 mm have room for only 2. Pockets are 10.2 x 3.2 mm, which should come out as a press fit. Use a drop of CA glue if one is loose. Use 8 x 3
  • Double-sided tape (thin) · Only for the 'tape pad' mount, for machine beds that magnets will not hold to. Stick it to the two flat wings on the underside.

Assembly

  1. Press the magnets into the pockets on the underside, all with the same pole facing down (4 on the default 70 mm guide). Add a drop of CA glue if any is loose. With the tape-pad mount, stick double-sided tape to the two flat wings instead.
  2. Lay a piece of your webbing with the tape on top under the presser foot and lower the foot onto it. Measure the free height from the machine bed to the underside of the front of the toe, about 3 mm in from its front edge. Set the 'Free height under the foot toe' slider to that before printing. The g
  3. Set the guide on the machine bed with the tapered nose toward the foot, so the nose tucks just under the toe without touching it.
  4. Feed the end of the webbing into the lower channel at the funnel end and pull it out at the nose. The webbing slides under the lips, so it goes in end-first.
  5. Lay the hook-and-loop tape into the upper channel on top of the webbing.
  6. Slide the guide sideways until the needle lines up with the tape edge you are stitching, then sew.

Good to know

  • If the free height you measure is under 7 mm (the slider minimum), print the guide at 7 mm and set it just in front of the foot without tucking it under the toe.
  • Each position of the guide lines up one stitch line. To sew the other edge of the tape, slide the guide sideways by the tape width, or set Tape position and print a second guide.
  • The webbing has to be fed in end-first under the lips. Only the tape can be laid in from above, unless the tape is as wide as the webbing or wider.
  • The presser foot and needle in the picture are representative shapes, not a specific machine. The nose check is against the free height you enter.
  • Magnets only hold on a steel bed or throat plate. On other beds, use the tape-pad mount. Magnet holding force was not checked.
  • Channel fit and position are checked in the engine. How smoothly real webbing and loop tape slide depends on their fuzz and stiffness. If a strip drags, raise the Side clearance slider (0.4 to 1.6 mm). If it wanders, lower it.
  • The floor raises the webbing 1.2 mm above the machine bed until it leaves the nose.
  • It prints standing up to 100 mm tall. Use the brim given in the print notes.
