I ummed and ahhed about which one should I get.
Finally decided small is very good for the gazillion of small items that need to be fabricated.
Woke up at 02:00, but since I don't use twitter, I go to Amazon.ca and looked at the small model that intrigued me: "Monoprice Select Mini". The build area is only 120x120x120mm. Can$203 for the black model, it will fit very nicely. Add a spool each of black and while filament. Place the order and be done.

This morning when I printed out the order acknowledgement (email) I went back to check the price on-line since I had seen funny things with drones and watches before. Within 5 hours the price jumped to $311.00. So that's $108 I don't need to spend. B-) B-)

Having an interrupted sleeping pattern was to my benefit.

As far as printing goes I have a list of things that are "wanted", with "a few more" to add. All of them within the build area; list will follow. :-B :-B

:-o I finally had to admit it today. My mental endurance i.e. being able to concentrate for 1 or 2 hours sure isn't what it used to be. And the same goes remembering whatever I learned using SketchUp. Basically it's back to square one with the 3D stuff. 8-| :-?

Testpiece for the printer, other than what is included from the factory will be the RhB track scale. That's how I found out that the old noggin isn't what it used to be. :ymblushing: :ymblushing:

Don't feel bad, HJ, it's not just you. I often look at stuff I've made and wonder "How the heck did I do that!?" when it comes to setting up stuff on the lathe etc. If I'm making 10 of something, and I've only finished 8, I make sure it's not more than a few hours before I get back to it and finish them...otherwise... :))

On the 3D printer front, my son says he uses OnShape, 123D and Fusion 360 depending on what he's trying to make.

Thanks Keith,

I looked at 123D and Fusion360, now signed up with Onshape.

In the meantime I'm constructing the track scale using SketchUp Make. :ymblushing: :ymblushing:

When I get stuck I delete the "problem", think about it and give it another try. @-) @-)
Getting very proficient with the Ctr+Z routine. :o)

There has been a "snag" with the delivery of the printer. Whenever I see a price that is that much lower and then snaps up by more than $100 within hours, it's lets see how this works.
New delivery target 1 to 2 weeks. ;) ;)
Of course I could cancel that order and reorder "ships from and sold by Amazon.ca" at a slight $80 extra. Not gonna happen! Spent a bit of time on their customer service chat to get a proper update.
One nice feature with chat, one can opt to get a printed copy of the conversation via email. B-) B-) No weasel work on that score, unlike a phone conversation. O:-) :)

In the meantime ..... more work on that track weighscale.

Getting my head around some of the SketchUp routines and the logical (?) sequence. Oh dear!

Machine arrives today, yesterday was re-organizing time at #40 to have the "spot" cleared and some other stuff stored.
Also been busy reading the user manual and other tips and tricks. =)) O:-) =))

Unrelated to topic: went to get the winter wheels installed, but since I don't like waiting around for hours and SWMBO was busy ..... I now have a confirmed appointment for Okt 23rd. Are these guys busy?? You better believe it!

Just because one reads in a review that is "virtually two assemblies that need to be joined" doesn't necessarily mean that it's true. (Fake reviews?) :ymdevil: :ymdevil:
The base comprising the control electronics, the Y-axis with the build table etc. comes as an assembly. All the rest needs to be assembled, installed, adjusted. It's not unpack start printing.
Anyway it's built, run to the homing position with the table to be leveled on Monday — yep, I need to look at scenery tomorrow, too much strain an the brain. :ymblushing:

The printer will be set up in the home office. Mainly because it allows for easy access to the support groups on the Internet — I don't intend to wear a "hair shirt" if it's avoidable.
Set up will happen after our Swiss guests leave on the 18th. ;) Household back to normal. #:-s

Tips and tricks - keep the filament in a bag with silicon gel sachet - its very fussy about humidity. You can try Tinkercad for online 3d modelling, very versatile and free. https://www.tinkercad.com/#/ Think carefully about orientation when printing to avoid support material, in some instances I have got a better result printing the model inverted. Be patient! good finish comes from high resolution and slow speed printing - overnight is not that unusual. And finally - THE PRINT HEAD REALLY IS HOT - do not touch it :)

Thanks for the tips.

The construction and printing orientation has been considered, along with a number of work-a-rounds that need to be tested.

All that said, first I need to recover from having visitors/guests :-o It all boils down to how much I like peace and quiet in the house and on walks. O:-) O:-)

Got the last parts to run the printer in the home office.
Before the stuff arrived I kept on reading and decided that switching from SketchUp Free to Fusion 360 will probably save a few surprises and headaches in the long run.
One of the nudges was reading this:
"Other than the problems described below, there can actually just be errors within your model. This is extremely common if you used SketchUp to do your designing. I do not have the exact reasoning for this, but it seems to happen with .stl’s exported from SketchUp more so than any other program."
Aranda, Sean. 3D Printing Failures: How to Diagnose and Repair All 3D Printing Issues (p. 58). Kindle Edition.

Another "discovery" is "Kindle for PC"; that should ease the learning curve, too. I'm old fashioned and learning via videos is just not my mode. Having an e-book open on the PC is more my style.

So how does it look?

Very convenient, everything within reach while sitting down. Learning material and user tips on the display. What's not in view — off to the right the coffee or tea cup

Saw the same machine nearly in use at Swanley last Saturday, cold sports hall meant it took some time to heat up. Once it was chuntering along quite happily. I've been told it is theoretically possible to print a fully operational gear train inside it's housing.
But, what material could you use to make such a thing that would work reliably?

Most likely nylon.
There are a lot of different filaments out there which could be tried.
