SPIRAL BRIDGE

thingiverse

<b>SPIRAL BRIDGE</b> <i>(AKA Pointless bridge)</i> This little bridge is intended for use on a 4mm scale model railway. It took ages to create and I hope it pleases someone. It prints well (see printer settings and notes below). <b>DIMENSIONS</b> (approx) - TOTAL LENGTH - 140mm - GAP BETWEEN TOWERS - 60mm - CLEARANCE UNDER BRIDGE DECK - 63mm - TOTAL HEIGHT - 80mm - STEP HEIGHT - 3mm <b>SUPPORTS</b> I have designed in 6 supports that enable this to be printed in one piece. The supports can be snipped away. (The blue graphic shows this). <b>FEEDBACK</b> I hope this will be useful to someone. If you get a successful print, please provide feedback and, if possible, a photo. <b>A REQUEST</b> I have found some of my designs for sale on eBay. Please do not use my designs commercially, they have taken me a long time to produce and I share them for free, not for others to make profit. I am pleased that some of my designs are being used to help raise money for an Air Ambulance charity. I was happy to give my permission for this.
