Preview of Flatspin
By Krypto
Complexity
Multi-part assembly
MAIN PURPOSE: Unwind filament from a spool lying flat
A low turntable for filament spools: lay the spool flat on the plate, feed the filament up through a guide above the printer, and the ball-bearing base turns as the printer pulls while the rim keeps 200 mm spools centred. Cardboard spools that squeal on rollers unwind smoothly lying down.

Preview of Rim Taper
By Krypto
Complexity
Medium
MAIN PURPOSE: Read bowl wall thickness at the lathe
Slide the tapered slot onto the rim of a bowl with the lathe stopped: it stops where the gap matches the wall, and the engraved number beside that point reads the thickness, from 12 down to 3 mm, without fetching callipers. Long jaws reach 90 mm down over a lip.

Preview of Skewer Gallery
By Krypto
Complexity
Medium
MAIN PURPOSE: Dry painted small parts without touching
Thread small painted parts, beads or model pieces onto bamboo skewers and lay the skewers across through the paired holes in the end walls: everything dries hanging in mid-air, touching nothing, the tray below catches drips, and four rods hold dozens of parts.

Preview of Stitch Clam
By Krypto
Complexity
Simple
MAIN PURPOSE: Hold leather for hand stitching
A leather stitching clam: glue a strip of scrap leather to the inside of each jaw tip, grip the long spring jaws between your knees and the faced jaws pinch the leather edge, holding it upright and still so both hands are free for saddle stitching with two needles.

Preview of Remaining-filament spool gauge
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Estimate how much filament is left on a spool
Rest the shoulder on the rim of a 1 kg spool's 200 mm flange and see which step the filament surface reaches: the steps mark 75, 50, 25 and 10 % left, worked out from the wound volume rather than the depth, so you know whether the spool will last a long print before you start it.

Preview of Bowden coupler collet clips
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Stop Bowden tubes moving in their couplers
Slide a horseshoe under the collet of each push-fit coupler, round the PTFE tube: the collet can no longer creep in and out with every retraction, which is what slowly wears the tube end and causes stringing and under-extrusion on Bowden printers.

Preview of Filament splice jig
By Krypto
Complexity
Simple
MAIN PURPOSE: Join two filament ends into one strand
Thread 60 mm of 4 mm PTFE tube through the holes in the two end walls, push a filament end in from each side until they meet over the open middle, then warm that spot with a heat gun and push gently: the tube keeps the ends concentric, so the joint stays 1.75 mm and feeds through the extruder. Spool ends become usable.

Preview of Heat-set insert plumb bridge
By Krypto
Complexity
Advanced
MAIN PURPOSE: Press heat-set inserts in square
Slide the printed part under the bridge with its hole below the bore and lower the soldering iron through the 11 mm guide tube: the iron can only travel straight down, so threaded heat-set inserts go in square instead of tilting and leaving a crooked M3 thread.

Preview of Two-handled spool rewinding crank
By Krypto
Complexity
Medium
MAIN PURPOSE: Rewind filament evenly onto another spool
Push the 52 mm hub into an empty spool, wrap a turn of tape round it if the bore is loose, and wind filament from a tangled, cardboard or refill spool with both hands on the grips: an even, steady wind with no crossed turns, which is what causes tangles and failed prints halfway through.

Preview of TPU dry-box filament grommet
By Krypto
Complexity
Medium
MAIN PURPOSE: Feed filament out of a sealed dry box
Drill a 14 mm hole in a dry box or a cereal container lid and push the spigot through: the 4.2 mm bore grips a 4 mm PTFE tube airtight, so filament feeds straight from the dry spool to the printer without letting damp air back in.
