Good luck with your 3D printing.
I had a miniUP! printer for 18 months or so, and initially, produced good results.
But how you form your cad model also has an effect on quality.
A major move on my part last Christmas, means I no longer have either of my printers.
The attached photo is of a horizontal steam engine at 1/10th scale. The file was for a full size engine.
This was a complete set of parts right down to the piston rings, and all printed successfully, but could not repeat this quality just before I gave the printer away.
Stick with one supplier for your filament, it varies so much, and remember - rubbish in rubbish out.
And it does absorb moisture, so keep it in an airtight container, with silica Gel.. until needed.
cheers
