Katsu router bushing guide
thingiverse
You can buy a palm router on Amazon for less than £40 which is pretty much a straight copy of a Makita model. The only problem I found with it was that standard base lacks the ability to attach bushings for template following. So I copied the original design and modified the opening so you can securely attach a screw in bushing.
