Would have to be diagonal, since it's total length -per Makita USA website- is 17.5 funny units, or 444.5mm. So pure vertical won't even fit in Sys3 M 437.
That what I meant by a "custom insert". Not sure it is worth the trouble, but, IMO, better than than a lone L337.
Funnty thing is, I got hold of a couple SYS MAXI for a good price recently and realized how much more practical they are for a (non-)site animal like me. While retaining reasonable portability. Just about when they got EOLed.
