What can you make with Wire Spool Holder Generator?
Caddies for 1 to 12 spools of up to three kinds, or brackets for a rod of any length. Makers print:
- A caddy for six spools of hook-up wire.
- A solder reel screwed to the bench.
- Wire on the wall above the bench.
- Brackets for big spools on a threaded rod.
How do you make a wire spool holder, step by step?
Everything is in the panel beside the holder, which updates as you change it. Start from a preset, then change what you need.
1. Start from a preset
Pick Hook-up wire, Solder reel, Wire on the wall, Big spools on brackets or Wire and solder. A preset sets only what it names; Surprise me tries another clearance and keeps your spools.
The presets and the caddy they make. 2. List your spools
Measure a spool across its rims (the flange), between the rims' outsides (the width) and its hole (the bore), and say how many. Add a second or third kind beside the first: solder, tape, a wider spool.
Six spools, 55 × 20 mm on a 25.5 mm bore. 3. Pick the rod
Choose a dowel or a threaded rod that passes every bore, then type what yours measures: dowels vary. Open cradles let the rod drop in; closed ones hold it for a holder that travels. Adaptors fill large bores down to the rod.
An 8 mm beech dowel in open cradles. 4. Set the comb
Measure your wire's insulation and type it: each bay gets a slot in the rail in front that narrows to a throat. Push the end through and it stays.
A 1.7 mm wire behind an 80 % throat. 5. Check it and download
The checks say whether the rod passes every spool and how long to cut it, whether the comb prints and how it fits your bed. Then download 3MF or STL.
The checks and the download.

Which print settings work best for a wire spool holder?
A caddy prints base down: its cradles and the comb's slots open upwards, so no supports are needed. Brackets print on their side, the rod's weight along the layers.
| Filament | Layer height to start | Thinnest wall | Supports | Notes |
|---|---|---|---|---|
| PETG | 0.2 mm | 0.8 mm | None | Keeps its shape next to a soldering iron. |
| PLA | 0.2 mm | 0.8 mm | None | Fine for hook-up wire, away from the iron. |
Tips for a holder that dispenses well
- Measure your rod and type it in: a dowel can be 0.4 mm off its size.
- Measure a spool's width over its rims, not the wire.
- Print the adaptors with the holder, a pair per spool with a large bore.
- Screw a solder reel's holder down: a heavy reel tips a light stand.
- Before you print, check it on the view's bar: Dimensions shows its size, Measure the distance between two points, Section cuts it open and Layers steps through it as your printer will.
What if the rod will not go in, or a wire slips out?
- The rod is tight in the cradles
- Type what your rod really measures, or run the Fit Test so the cradles take your printer's fit.
- The checks say the rod does not pass a spool
- Press Apply for the thickest rod of the table that passes every bore.
- A wire slips out of the comb
- Measure the insulation again and pick a narrower throat.
- The caddy is longer than the bed
- Leave Split to fit the bed on: it comes in modules of whole bays, the rod joins them.
