After consideration of the design improvements and improved rigidity that can be achieved with the 30/30 extruded aluminum upgrade to the already great Prusa i3 MK2 I’ve put together an order for all the components needed. I did however run into an issue where a couple parts required were not in inventory. With a little more work by ordering a couple rods for the build that are over sized by 5mm in lengths I have been able to order all the components needed. I do have the ability to cut down to the correct size the rods for this build so they are the proper size.
Update!!! Many of the STL files have been improved and updated
Some useful information in brief as to sourcing parts for the build are outlined below in an effort to help streamline the process for those interested in the upgrade. For all components you will first need to create an account, LOGIN then add components to your shopping cart for each vendor involved.

I encourage you to read and carefully review the information available at the github website so you have a full understanding of what is required to successfully complete this upgrade. It is rather straight forward so just pay attention when ordering all your upgrade parts. You will also need to Print all the new parts for your upgrade so this is the chance to make a color change if that tickles your fancy.
Optional Y Carriage if you do not already have the MK2.

The only one that you need to worry about is the spacing of the left y rod holders.
On the reference build, each left y rod holder is 67.75mm from the edge of the extrusion.
Ensure the front and back measurements of the left side are the same. Then using the the bearings and the y carriage, ensure the right side y rods are parallel and the y carriage ride smoothly. if needed adjust position of the bearing holders so that the y carriage slides smooth.
- build on a level hard surface and ensure the frame is square as you tighten the frame bolts.
- when installing the frame braces, tighten them but don’t go hulk strength and crack them.
- I found fender washer for the y carriage bolts spread the load and help maintain consistent contact
- make sure you use the correct length M6 screws, most pieces use M6 x 12 but others use M6 x 14,
- M6 x 12mm screws should be used for the parts that have recessed holes. Namely: Y idler and motor holder, the Rambo mount holder and the Z Rod Holders
- M6 x 14mm screws with washer should be used on L and T brackets
- the firmware changes are optional. you can make this work without making any changes by moving the gantry so tha the nozzle is 210mm from the print bed
I have some screen shots below of the parts I’ve ordered and will soon update this page to share my progress and give my thoughts on any performance improvements I experience.
