most useful extra tools for assembly of the kit and a tip for sec#7/17
Having these tools in my box made several steps easier that said I would not buy a $40 torque driver just to assemble a printer kit but it gives a person like me a bit of extra comfort when assembling things with delicate fasteners
Re: most useful extra tools for assembly of the kit
And a short note on how I used the Torque screwdriver in one of several places where SS 3mm fasteners are going into metal threaded items.
from assembly section 7 Heated and PSU section 17
I also used a 3mm tap here to clean out holes for these screws just on the basis of it being good practice to clean out threaded holes after a part is painted or powder coated. Also using SS locking forceps (or plastic kit builders locking forceps) to place all but the centre spacer where a tie wrap end was perfect for the job. I tightened all of them in the approved pattern with a torque screwdriver to 10 inch pounds and some guidance here on what PRUSA would like for a number would be nice… I would not want to go above 30 to 40 inch pounds with ss fasteners into aluminum threads with fasteners this small but even torque on each would seem to be what they are looking for.
locking forceps or locking tweezers are cheap, the ones in the post above are just $5 a dozen including postage less than 42 cents each and I am sure in Bulk would be less than 10 cents each should Prusa want to include them in the tool bag and of course you could 3d print them in something like PETG I have a selection of actual forceps in various sizes and types courtesy of my doctor who had a bunch that came with his practice that can no longer be used as the nickel plating has chipped so they cannot be safely autoclaved today they are made of stainless steel I believe and are also quite reasonable for the "hobby grade"
I am a large person 6'6" or a bit over 198mm tall and about 244 pounds or 120 kilos and my hands are large in proportion add in a bit of essential tremor and I would not have been able to wire up the ENSY without my Kelly Forceps so for me they are essential tools for this kit and not just useful extras.
these are the most useful type that I grab every time. they are called Kelly Clamps

$4.30 each

Great idea for a thread!
I would add, having a squaring tool might be useful to ensure there is no axis skew. Unfortunately finding a square that is actually square enough for our application can be costly, however one can simply buy a $5 dollar steel square, and then use a hammer and nail to fine tune that square. Myself I've printed one that proved to be square but probably only because my MK3 reports 0 skew.
The square can also double to help true the bed flat manually before doing any einsy mesh leveling.

a Very good point I did not think of that as I use high accuracy squares all the time in my home machine shop Mine I have had for almost 60 years and I inherited them from a great uncle who also left me some of his machine tools and got me started with metalworking about 5 years before he died that are Starret brand and today they would cost you between $100 and $300 depending on size and they stay in their case for all but the most precise toolmaking work.
But very good quality imported ones can be had for much less and I use these all the time and leave them about the shop.
this is the smallest
and is a bit too small for most checking on the printer it is about $12

this one is the size I used and is just a bout $5 more

but many folks will buy an import set of 5 different sizes. I favor this design as it is more robust than the thin blade designs and as they are my day to day tools they do get knocked about a little bit.
Having a square you can rely on is a calming item in the workshop... once you get one check it against a farming square and you may get a surprise. it might be dead nuts accurate I have an old speed square that passes based on the import type above but against a Starret master reference square light can be seen when brightly back lit... 98% of the work I do in the shop it would be fine as these days I seldom have to work to +- 0.0001 inch as I get older it gets harder as things like the temperature of the workpiece and the machine bearings and ways of the machine also affect things at that point.

I had a request for the link to the metric ball end hex bits with the long shank
