I am doing a metric-based build. My BoM is currently:
1 pcs of M8 Threaded rod
1 pcs of M8 (130 mm)
12 pcs of M8 (65 mm)
2 pcs of M8 (40 mm)
28 pcs of M8 (30 mm)
19 pcs of M3 (10 mm)
57 pcs of M3.5 (20 mm)
1 of M8 (25 mm) - Coupling nut
43 of M8 Nylock Nuts
57 of M3.5 Nylock Nuts
My question is, since bulks are often cheaper; cant i just collapse this into:
1 pcs of M8 Threaded rod
1 pcs of M8 (130 mm)
42 pcs of M8 (65 mm) <- here
19 pcs of M3 (10 mm)
57 pcs of M3.5 (20 mm)
1 of M8 (25 mm) - Coupling nut
43 of M8 Nylock Nuts
57 of M3.5 Nylock Nuts
Also, I haven’t seen any shops (im from Denmark - Europe) that sells M3.5 - what is this size? Can an M4 do? M3 ?
Just quickly looking at it, m8x30 can’t go much longer in many cases maybe 35/40 but that could be pushing it.
For the most part, I really really tried hard to minimize part diversity. So There isn’t much room to condense other that a few here or there but at that point If you have to buy one you might as well get all the right ones.
I’m going to use M4, it does mean you will have no movement to adjust squareness, I am only part way through printing the parts, I have put a 4mm reamer through the holes because on my printer they have printed out just under 4mm, I also have a set of drills in 0.1mm increments should I need them.
