    So, the B.O.M. has no measurements and after ordering a few parts that don't work and then using the measuring tool in an STL Viewer, I thought I'd post my findings so no one else makes the same mistake.

    The U-Groove Bearing is a 4mm(ID)*13mm(OD)*4mm(w). I found them on Amazon here:

    The heatsink I'm still looking for, the first one I tried was this one:

    It's dimensions are 50mm(h)*25mm(w). After using the measuring tool, it looks like the heatsink being used 13mm(h)*14mm(w), although you might be able to get away with it being 20mm(w).

    The drive gear is 11mm(w) but I'm using a 12mm(w) and so far it seems to be ok. Here it is on Amazon:

    Also the heatsink can only be around 15mm(h).

    Hi! I was wondering how to 100k thermistor was attached to the 40 watt heater, and in addition, whether there was a certain brand/model of heater you recommended. Thank you for your excellent tutorial!

    In addition, the parts list calls for a NEMA 17 motor while the image shows the one you're using as a 16; would either work? Thanks!
