3D Printing - whether to buy, what to buy and how to use it?

I have been getting vertical "corrugations" which as far as I can make out is "chatter" from which ever axis step motor isn't moving at that time
That's often explained by differences in printing speed caused by the head slowing down for overhangs, eg the strapping and bolt heads. Occasionally when quality is important I'll dive into the settings and set every speed to the lowest speed in the settings chosen.

Another issue can be vibration on changes of head direction when printing fast. There are calibration routines to tune this, Bambu printer have a auto tune function as standard.

Generally I prefer to break designs down so they all print on the horizontal as that tends to make surface details crisper. Maybe not so easy for this design when you have detail on the inner faces though.

Toolbox for the X2D toolkit. This is one of a million free downloads of variable utility available on the Bambu site.

PLA, 0.4 (standard) nozzle. It took about 4 hours to print the three parts all in default settings.
I can see the lid and clip being re-used, and alternative bases being designed to suit other sets of tools. This or another of the available designs.
I think it did tell me how much filament it used, but I didn't make a note. It weighs 180g so I guess about £2.30, not “cheap”, but given a specific toolset, and will be used hopefully for years, probably quite good value.

This also suggests that the modelling uses (eg timber wagons) will be quite economical. It’s never going to replace resin, but I’m sure there are applications for which it’s much more appropriate, Templot COT track being high on my list.

This seems to be different to the "speed change" issue, I will try and get a photo but it is a regular, constant pitch vertical line, on all 8 faces. My sons printer (same model) has the same issue.
