I heard the MakerBot needed new resistors so I tried to find out the part. Using [http://farm5.static.flickr.com/4138/4883619302_73989096cd.jpg this photo] I determined that they were 5Ω, 10Watt aluminium block resistors with a 1% tolerance. I checked Rapid, RS, and Farnell for this part but only [http://uk.farnell.com/ohmite/810f5r0e/resistor-wirewound-5ohm-10w-1/dp/1159146 Farnell had them in stock]. However they were £8 each and required £16 shipping from the US so I bought [http://www.rapidonline.com/productinfo.aspx?catref=62-8077 these alternatives from Rapid] (62-8077) which have a 5% tolerance. | I heard the MakerBot needed new resistors so I tried to find out the part.

However, it turns out that they were physically too small and wouldn't align with the heater block mounting holes. So I've had a look at the [http://www.thingiverse.com/download:9720 heater block plan] on [http://www.thingiverse.com/thing:3290 thingiverse] and the fixing hole distance is apparently 15.9 mm or 14.3 mm. Looking at the [http://www.ohmite.com/catalog/pdf/89_series.pdf datasheet for the Farnell US stock] the B and D dimensions of the 10W 810 series are almost identical - these are the ones to get. | |||
So it turns out that I should've ordered them from the US. | |||
