I’m wanting to tackle a small build volume 3d printer for the sole purpose of building parts for a larger 3d printer with the goal of giving the mini printer to my daughter when I’m done. Any advice on where to start? I own an OX router with a cutting area of 19x29 inches and will have a 40w laser tomorrow with a cutting area of 11.8x8 inches. I would like to document the process along the way for anyone else that has either of these pieces of hardware and would like to jump into the 3d printing arena. Thank-you in advance any suggestions are much appreciated!
Yes try the DICE
@Rene_Jurack is the Dice a feasible project for me with the parameters I listed above?
@Alex_Krause I have a Printrbot Play I use for precisely this purpose and it works great. I could spring for a heatbed and larger bed option but the PLA wprks fine.
Get the play,
Proven design, quality prints, low price, and auto leveling.
@Samer_Najia I’m looking to build this one on a budget so I have the needed funds to build the OpenCNC v2 
Of course, me included. I also put together an MPrime 1 recycling most of the parts from my SmartRap. I also have the CR7 and that was cheap. If I can help by printing parts for you let me know.
I was kinda thinking a ITopie by @Sebastien_Mischler might fit the bill for what I was looking for
Well personally I sprang for a hobbyking turnigy fabrikator mini precisely because it was extremely cheap. If this is interesting I’d definitely reccomend you read up on the history though, Hobbyking were not particularly nice about the Tinboy IP (it’s based on the Tinyboy open source design)
For about $200 (us) you can get the franknbot kit from printrbot. Small, no frills and all the main stuff you need to build a 3d printer.
I designed the M Prime One (http://mprime.io/m-prime-one) to be simple and economical, I think it may be a great option for you. The frame fits in your OX router/laser cutter, so you can make one very inexpensively out of MDF (and machine the dibond bed too). It’s small, has a handle to carry it around, enough printing volume (200x150x150mm) and very common electronical/mechanical parts, easy to source. Being very simple and with few parts, once you get a couple of things right it’s very easy to calibrate and not many things can go wrong, that makes it a very good starting printer. Let me know if you decide to build it and we can help you.
By the way, thanks to @Samer_Najia for suggesting it too, I hope you are happy with your printer =)
