Beat Saber block - Sliced + Magnets, no AMS

Remix of Devious Cat's excellent Beat Saber block - but, a whole block means it was missed! I cut the model into two pieces and added embedded holes for four 10x2mm magnets so the two halves snap together (with a pause at layer 13). That does mean it can't be resized without extra tweaks, so this version is at 75% of the original - still plenty big!

As an added bonus, no base-plate fillets are needed by printing slice face down.

I included a few different scales of arrow - the middle size worked for me.
