stung by wasp while building extruder nw playing pickup
dozens of parts on the floor some fasteners may be between the floor boards guess the spares bag will be needed... oh well I cant seem to find one of the BondTech roller bearings but I found these on line will they fit?
INA K3X5X9TN Needle Roller Bearing, Cage and Roller, Single Row, Polyamide Nylon Cage, Open End, Metric, 3mm ID, 5mm OD, 9mm Width, 50000rpm Maximum Rotational Speed
Called Prusa, and yes they were very nice... happens all the time they said and said they would send me one for free if I bought a spool of filament... I consider this more than fair as I lost it so its all on me...
But I elected to order a few from Bondtech only $1.20 each if you buy 10 and $1.60 each for less than 10 shipping via fedex letter for $16 or so. Looks like it is not hard to replace the bearings in an assembled printer so I will press ahead with the build... i wonder if it would hurt anything to do the test and setup stuff with just the one bearing? The ones I found online above were 12 bucks each and would be shipped "sometime in December" Pass I get the feeling some places still don't understand internet marketing.

Just a suggestion/hint. There are a few crevices in the table we assembled ours on, so we covered the whole tabletop with blank newsprint (packing paper or other will do), taping all the joints with painters tape.
You might consider something similar on the area of the floor you're working on--it might help avoid these little inconveniences... 😉
That's "MISTER Old Fart" to you!

Wise words for next time 😳
found them all except for one of the Bondtech needle bearings. and Bondtech says I will have the replacement (bought 3 actually as $1.60 each is not much against the FedEx international $16 fee) and so I will have them Monday afternoon at a guess the tracker say by 6PM
interestingly their web site says these should be greased with light lithium grease before use and that is not mentioned in the assembly guide. so I have slowed down the build just finished #7 Heated and PS.
