R8 Collet Holder - Rotating - 18 Count

I was looking for an R8 collet holder for my Bridgeport Series I mill. I had yet to purchase a rotary table or DRO so 3D printing was the next best option for this. Note the base is threaded for a 5/16 x 20 bolt. I never have luck 3D printing threads, but these cam out quite nicely and with just the right amount of force the bolt will screw in. I printed with straight PLA, 40% infill, but this is very strong. 10% will probably be sufficient if time or material costs are a concern. Does the job well. I appreciate any comments or build photos or PayPal donations to thank help fund my Fusion 360 license in any possible: http://paypal.me/JamesKeane18
