I had already made several of these, but they wont fit on the Raffle Alu-Block,Alu-Carriage & 3-in-1 extruder combination, so i could throw them is the spares bin or experiment, it turns out all that is required is a second set of screw holes 3 mm back from the originals (with relief in the upper fillet for the screw head to seat flat). this would make the part more universal. So a fully functional remix would involve only these minor changes.
I have done this in tinkercad, but lacking the original cad files, the fine details of the original work are lost. tinkercad's import of STL files works, but many triangles are lost and the model becomes rougher. I hope the addition of these 2 holes is adopted by similar designs so users of these type of upgrades can have the benefit of those designs for their upgraded bots, while mine is functional, it is by no means better. (the last photo shows the remix and the chamfered relief into the fillet to allow the bolt to seat fully on the new forward hole.
the 3mm was added by Carl Raffle on the Alu-Block to eliminate the need for 3mm spacers between the block and the extruder when using more mechanically complex extruders Like the 3-in-1, Felxion etc. and for Makerbot 2x compatability, and to encrease cooling block stability and performance vs. the spacer.
I know remix requests are a dime a dozen and time is precious, but please consider this one in the spirit it was intended. it would give many users other than myself the benefit of the revised design.
I will post a make, with photos, but I don't think it deserves to be a remix.
