Are you going add dowel pins to make the holes in the parts?

there's about 35 pins , yeah - a couple in the middle of the squares are just alignment, not touching the plastic part
i will knock some of the sharp edges off, too, where appropriate - just burnish a bit to round

could you give some more information on where to find hobby-size injection moulding machines and what they cost etc ?
what are the considerations/limitations when making a mould ?
thanks !

this is the best i know for ready to go desktop machines.
i'm sure there are others somewhere, though.

Been using equipment from this company, works great. Some of the products could be home made I think.
