Need a bigger print bed... love Prusa mk3... still love my MP Mini

My MP Mini has been a great workhorse, giving me the entry into the 3D printing realm with plenty of fun and learning experiences, although it's entry level print bed size (110x110) is just a little too small for some of the projects I need to for the Model 3.

The Prusa i3 MK3 keeps shouting out to me to buy it, but then I stumbled across a few more hacking links for the MP Mini....

Looked like a reasonably interesting route to allow me to still have the fun with the mini, push the print bed size and save a few $ without jumping to the $$$ point of the Prusa... I'm sure it will shout louder at me in the future, but for now the single colout mini will still surfice and after trying a small sample of TPU successfully, it was time to get cracking, get some aluminum and dig out the hacksaw ....

Using the old bed as the template is great - but use it round the correct way i.e. not this way !

The difference is that you will have the slots for the timing belt aligned correctly :)
