CraftKutz (Final, Working!)
by bstory2001, published
Spring loaded craft cutter attachment for RichRap's awesome QuckFit carriage. It allows for the blade tip to be aligned with my Jhead extruder so there is no mucking around with Z stops and such when I switch over.
This is a complete do-over from a previous attempt that was overly complex and worthless. Keeping it simple.

What you will need:
1 - Quickfit housing print
1 - Top plate print
1 - Collar print
3 - ~11mm springs from cheap "Bic Pencil #2 0.7mm" mechanical pencils. Mine are 3.5mm wide and 11mm +- 1mm tall uncompressed.
1 - Vinyl cutter blade holder that is around 11.5 mm diameter. ( http://www.ebay.com/itm/330651969471?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 )
*And some tweezers help to get the springs installed.
It seems pretty straightforward but the order of assembly is important to prevent disassembly reassembly.
First check that everything fits and file/sand if needed. Check the Top Plate to its slot, the vinyl to its hole. Check that the Collar print fits onto the tool(disassemble the tool for installation). Check that the springs fit it there holes.
Assemble in this order.
1-install vinyl tool in its hole.
2-Slide the Collar onto the vinyl tool.
3-Push the Top Plate into its slot.
4- Fit the springs in with some tweezers.
5- Put the guts back in the vinyl tool.
The idea is that you set the blade for the depth you want to cut, then let the flat nose drag around on the material. And you don't need to readjust the z-axis to change it out ever! The vinyl tool fits in snug but loose so there is no wobble. The springs give it some cushion from imperfections in bed levels and also holds the tool tight to the paper, vinyl, whatever.
