Riser blocks for Y/B feet (spare)

Spare riser blocks for under the Y/B axis feet.  

This listing includes 4x riser blocks.  No hardware is included.

These blocks are 8.3mm thick.  They are not stackable onto themselves.

Please note: 

These are only required for the Foreman sized machines and are included with every Foreman sized machine.

We added this listing as some users of non-foreman sized machines wanted the riser blocks for their own various reasons.
