It turns out the BOM i was using from the Reprap Huxley page isnt complete, and i needed to buy some M3 hex-head machine screws in 30m, 20mm, and 12mm lengths.
I went to RS, where i had gotten my other hardware from, and priced them up... and just about had a heart attack! £50 extra on bolts wasnt something i really wanted to spend, so i went back to my old love, eBay!
There are loads of sellers of nuts and bolts and associated fripperies on eBay in packs of 100+, and you can decrease your parts cost by a LOT by getting nuts, bolts, washers etc from one of them.
After some discussion on the #reprap IRC channel, i settled on eBay seller 'boltmeup'
RS Price: £50, eBay Price: £14!
Also, i compared the stuff from RS i've already bought:
| Item | RS Price | eBay Price |
|---|---|---|
| M3 Nuts | £4.85 | £2.95 |
| M3 Washers | £1.66 | £1.15 |
| M6 Nuts | £8.30 | £7 |
| M6 Lock Nuts | £7.34 | £6.50 |
| M6 Washers | £3.03 | £2.78 |
| M6 Mudguard Washers | £4.87 | £3.80 |
| £30.05 | £24.18 |
Only a £5 saving, but add that to the £36 saving from the bolts and it comes to enough for 4 pololu driver boards!
