Universal Blade Holder

I didn't want to spend $100 on 3 screws and 2 pieces of aluminum/steel.

Behold, my version of a universal blade holder!

BOM: 

2x M4 screws (20mm works great)

2x M4 nuts (Locking nuts preferred)

4x M4 washers

1x M6 Tap (If not using Heat Set Insert)

1x M6 Heat Set Insert (If using)

1x M6 screw (I will be using a thumb screw in the future - a 30mm screw works, but I need to test for the Heat Set Insert still.)

There are 3 objects included in the file. 

1 object uses 3d printed threads - These threads need to have an M6 tap run through them to work. 

1 object has a tower for an m6 heat set insert - The Heat set insert is meant to be inserted from the flat (build plate) side of the model, into the tower. 

1 object is the second side of the blade holder. It has a 100% infill cylinder for the jack screw to land on. 

Each holder has 4 M4 screw holes. Only 2 screws need to be used, but since different blades have various features on them, you have options in case the inner most holes are fouled by features on the the blades you use. Install these screws loosely so the 2 pieces can move. The cylinder on 2nd half that the jack screw lands on is intended to maintain a gap to make it easier to slot blades into the holder.  

Once blades are slotted in, tighten the M6 screw to clamp the blade in place. 

These holders will work with True blades and should work with any other brand or type of blade. Haven't tested with Goalie blades, but should also work.
