ok 🤞

Raining outside so back to drawing... adding Nema11 stepper(built in 1:100 reduction) + worm/wormwheel to altitude axis. Need two of these :

At our age we need to make the best of it...
-
That makes two of us...

Nice..! Thank you...!

I have no problem at all you calling that 'thing' ugly Gina... Rigid..? Well the thickest branch is about 12 cm diameter. These three thick branches set in a triangular formation, no doubt about that. In fact my point is (first of all it saves me lots of time making this tripod) I wanted to make a combination of that very rough looking tripod combined with a piece of high tech-telescope on top of that rough piece of wood. It's that contrast I like very much. On thing is certain, it'll be an eye-catcher during open door mid September. And I'm pretty sure many people will repeat these words you just posted here : It's certainly different! Each time someone says that during OD, I will smile and think of your words.

Think I might have found how to make very sharp edges 'painting' a printed surface. I used masking tape and at first I pressed a tick black marker very hard half on the tape, half on the printed surface. Surprise because even I very hard pushed the masking tape onto the printed surface, it gave me this result : Second I tried another approach, instead of pushing both on the masking tape and the printed surface at the same time, I veeeery gently rubbed with the marker alongside the masking tape, and see what happens : Both techniques side by side : FYI, the flaw in this part is : I forgot to change settings in my slicer. So when a 0.7mm is set where 1.5mm should have used ...🙄

I'm not at all happy with that result at all Gina, let that be clear, I said 'better' not perfect. That is spoken as a 3D-printing 'nerd'. A regular visitor(at our local observatory) will not judge it as I do of course. I'm only happy with it because of the hight of this rocket. It will be 'out of reach(view)' to the visitors. Nobody will notice the so called 'bad' quality.
-
Better, not perfect. It's only a few millimetres 'big' so, It'll do... Need four of these. Manoeuvrability of that upper stage is secured now with four of these thruster units...

SaturnV project is finished, now I can continue working on this one. Today I made a first attempt to make a sturdy tripod for that bino. Well imo this is a sturdy one, and heavy too..😁 There will be two platforms. The first one, the highest branch, is for the bino itself. That smaller branch(mid-right) is for a smaller platform holding eyepieces and stuff. Both still need to be cut to the correct height. It's wood btw from an apple-tree. It's old, full of moss, very irregularly shaped, I love it. The bottom is a sandwich of 3 layers 18mm plywood. These will be painted green, about the same colour as the branches itself. All is bolted together with thick hex-head wood-screws.

I'll gather all stl's and post them here.

Gina, If you do print it, this size, I'll send you a set of labels (if you're interested).
-
If you lost it : 1.5mm nozzles are not for sale(if I'm not mistaken) Gina...
-
You do have a 1.5mm... I know for sure...!...;-)
-
If I'm not mistaken the height record water rocket launching is set at 530(!) meters. but these guys used kevlar to reinforce they’re rockets... Just kidding guys...;-)))

Nono I'm going to add self adhesive plastic labels and lettering. Tried it a long time ago, painting PLA. For some reason it's always a messy job. Applying paint the edges always tend to finish up kinda 'fuzzy'. I want a absolute clean and sharp edge for all these coloured surfaces and lettering.
-
Maybe I could add a water-rocket-launching system...;-))
-
Do you know were you stored that 1.5mm nozzle Gina...;-)))

As a matter of fact, these printers I have... the best tool I ever had. The possibilities are endless. And no, the limit is not the size of the printer.
-
Indeed..
-
A few hours later .... I'm at 1.7 meter now Still busy printing thrusters @0.4mm nozzle. Takes a long time. I wanted these thruster high quality, that's why 0.4 And yes, still struggling with these tiny upper thrusters...😡
-
Almost done printing. Still a few flame deflectors, ailerons and thrusters to do. I have a few orders for this rocket already. Meanwhile just started assembling my first SaturnV. The cross shaped part is there to guide the most upper part with a threaded rod.
