mk2 PINDA Aligning

 I've making good progress in constructing my MK2 varient  and I need to set the correct P.I.N.D.A. probe height.

Luckily, michaell0533 has made a model for this.

Prusa Parts and Kits

 Prusa printers have some slightly tricky parts if you want to build one from scratch.

Bluerolls have a store on Aliexpress with MK2 and MK3 parts and kits, including packs of specific small springs, and gears that are difficult to source.

Open Source Router Plans

There is an interesting open source router called a TopsCnc that can mostly be made using 3d printed plastic parts and also aluminium extrusion.

I'm not really sure I have a purpose for such a machine, but it is curious.

Project page is here.

A bit beefier is the PrintNC. Looks pretty simple to put together.
