Custom blocks for the FLT4 frame.
Dark Mage Cutts block
Anti block
Balance/juice style block.

The DM Cutts and Anti block require M5 threaded inserts. I advise reaming with a 7mm bit prior to installation. The balance style block bolts in with the axle bolts. The holes will require reaming out with an 8mm drill bit.

I advise a brim for this and you can block supports inside the H block chamber cut out.

M5 threaded inserts. Screw in or knurled. I used screw in. I reamed the holes at 7mm and heated the inserts before screwing in.
Ream the balance/juice style block axle holes with an 8mm bit.
