I picked up the Smartrap mini about a year ago and tried to build one. Well 10 months, and a lot of CAD and build time later, I have revised and updated the parts for this little printer. I really like this design, even with its flaws. It is low cost, simple to make, and takes a minimalist approach. People like it years ago, and there were actually too many forks I think, people got lost in which parts to get.
I am sure this will make it worse, but I put the parts files and cad files on a google site and also on Thingiverse.
I have some additional improvements I would like to try so keep a watch out for these.
I can also make plastic parts sets for a small fee. It takes about 24hrs of plate time and 1/3-1/2 roll of filament.
PM or email if interested.
Thanks for reading. Feedback appreciated !

Scary, not serious? I suppose. There does not seem to be much interest.
Vintage? The original designer started about 2013, the last thingiverse spins were in like 2016.
My machine, when running well, makes better parts than the Anet A2 I have. And I use my SR2 2-3times as often as the Anet, which is nearly everyday.
But remember in the overall landscape here there are dozens and dozens of designs, people tend to want the latest and greatest thing.
Some people have lots of money, if you are buying a Lulzbot for $3000, those folks dont reprap.
I think the audience is the person familiar with 3d printing, by using one, but who wants to know more, or wants to experiment.
That does kind of narrow the field doesn't it?
I wanted to learn all the ins and outs, but had little money, and this type struck me as requiring a minimum of space and materials.
There also seemed to be a great deal of lessons learned missing from the records, I was curious.
The glass(I use glass as a build plate) can slide around, but I have simple idea to fix that.
I am trying to think of a simple, cheap effective way to get a heated bed and removable metal or plastic 'plates' using magnets.
This should fix the glass moving slightly.
Its open style is appealing to me. It actually sits in a corner of a desk very well.
These pics with wiring everywhere are part of the assembly pics, once all the wiring is bundled, its much cleaner.
Assembly and tuning video
Better assembly doc/pdf, I dislike the slow loading webpage.
Mods for better parts that assemble without so many screws.
Mods for extruder bearing holder (still todo)
Mod to extruder for flexi filament, it will print TPU, but needs more support at the bearing/gear
