RE: Tools: What do you recommend?

Well, most of what I print is not rocket science.  😉  😉

A good bit of what I print ends up in the garbage.  3D printing is not rocket science, but it is a tinker's dream.  

I keep a left over Hatchbox filament box on the table beside the printer for scraps and failed prints, and it seems to get full every 1-2 weeks, mostly with things like priming strips, skirts and supports.  There's a lot more wastage than I thought there would be, and I wish our area's trash hauler would accept 3d print scraps with the other recycle plastics.

My goal is to have an optimum level of usable prints with a minimum of frustration and futzing around.  The MK3s, so far at least, has been good at keeping this goal.

A deburring tool is essential.  I prefer an aluminum handle.  AliExpress has the one I use for sale.

RE: Tools: What do you recommend?

Here's a good question for this thread.

In the thread about doing advanced bed leveling using a straight edge, the video shows what appears to be one of those flat-blade drywall tape tools used as a straight edge.  I asked exactly what it was in that thread but received no response.  The other day at the local hardware store I looked at the drywall tools and held two of them edge to edge as a sanity check, but I could clearly see daylight between them so I guess those were not truly straight.

Anyone have other suggestions, other than a machine shop grade professional straight edge?

I guess I could look at Harbor Freight or even Home Depot for something of better quality.

I think I'd just flip it and look for an average. Then again, I don't worry too much about a perfectly flat bed given that we have MBL and removable print surfaces. If I had a badly warped bed I was trying to level, I might buy a better quality straightedge.

@charles-h13

for flat parts this works very well, but with non-planar or freeform surfaces it becomes more difficult. I always do this with the soldering station at about 300 degrees C., drink some target water beforehand and carefully press the inserts with a conical 2mm tip into the pre-machined hole. This works very well if you have some practice.

I use some hardened hairline gauges in different lengths like this one:

I use a lab glass block like this: https://www.amazon.co.uk/Eisco-Glass-Rectangular-Block-125mm/dp/B01BW05LPA/ref=sr_1_7?dchild=1&keywords=eisco+glass+block&qid=1599200545&sr=8-7

(But got it much cheaper)

I think it may have been Bobstro whom wrote an initial printer setup piece, but basically you use the accurate glass block to get your axis exactly at 90 Degrees to each other as part of the initial setup of the printer.

My skew is actually 0.0 as reported by the printer.

I print nearly exclusively with PETG and now only use nickel plated copper nozzles.

For cleaning the nozzle if it simply wont peel off, I use the brass and fibreglass brush from this set: https://www.amazon.co.uk/Proops-Brass-Fiberglass-Scratch-Postage/dp/B00IUGYADE

Although I can't actually remember the last time I had to use them! (May have been whilst I was still using brass nozzles), if I get any build up, I just get some PETG filament, melt it all over the nozzle, drop the temperature and when it hits 140 Deg C, I just pinch the PETG with the copper tongs and it pulls all the PETG off the nozzle like a skin. But mostly I just pinch off any deposits using just the tongs at the start of every print if there is anything on the nozzle that is.

With filament colour or type changes and nozzle changes, I always purge with cleaning filament, followed by PLA, turn off the heat and do a cold pull. I have never had a blocked nozzle or a leaking nozzle or any nozzle issues in 2 years so far since ditching brass.

Brass nozzles and PETG whilst it works, just caused problems with boogers, burnt bits, poor printing etc and no amount of scrubbing could remove every last trace of PETG from the brass.

Normal people believe that if it ain’t broke, don’t fix it. Engineers believe that if it ain’t broke, it doesn’t have enough features yet.

I do high power rockets up to 15K so isert sare often a must!

What does it mean "15K" - they go up 15 kilometers or is it some kind of power index?

Really? How much weight of blackpowder do they carry at start (is that still blackpowder)? And how is that possible on the legal side. I am flying RC planes in Austria - altitude for flying is limited to 150 meters (I think) over ground.

Do you have any easily-accessible online photos of your rockets?

I would also like to see such a rocket in action 👍 !

I do parts that are 3d printed.  Most are fiberglass, paper, and wood.  

Here is my level 3 build thread from a few years ago.  It has gone up to 3 miles high

RE: Tools: What do you recommend?

Those are awesome!  I'm assuming those are powered by those disposable rocket motors, correct?

When I was maybe 10 years old we had a model of the Aerobee Hi, which was said to be the basis of the Able, Vanguard and Thor/Delta second stage which used small rocket motors.  We had to shoot it off in an open field in a city park, as it would go maybe 500 feet and drift several blocks on the return trip.  We fired it with a lantern battery.

Yours are obviously more powerful and sophisticated.  58lbs!  That's quite a rocket!

Wow, very good start and clean landing 👍 👍 .

Did you develop the construction plans yourself or do you work from templates? Which fuel do you use?

In Austria I have not yet seen something similar live.

The motors are partially reusable.  They come as a reload that fits in a 75, 98, or 150mm aluminum casing (tube).  I have flown rockets as small as 13 mm up 30 inches in diameter.  3D printing has revolutionized my construction methods.

There are kits.  That rocket is a 50% scale of a NASA sounding rocket.  

The Nasa Version was: 

Height 6 m (19.685 feet)
Width 0.43 m (16.9 inches)
Mass 709 kg or 1500 pounds

I build a full scale model that has never flown that is 17 inches in diameter and 20 feet long.  It only weighs 220 pounds (99 kg).
