thingiverse

Hi All.I was searching for Tube rings for this lense and could only find for the F 2.8 version.I tried to adjust that model but ended up designing my own at the end based on my own design for the Evoguide ED50 Guide scope. ( Not published yet )There is some accessories plates to attach various equipment and cable management to.I also added an additional Dove tail plate and a finder scope / Pointer for orientation in the sky.The Clamps are a perfect fit, if not tightened too firm one can rotate field of view ( the lence) without any effort and it is still snug without movement when imaging.The files is project files from Prusa slicer. And the Pinrui Silk PLA have given no bad prints as of yet. seems solid and durable. Each print takes approx 3 -4 hours + - , with my settings, PLA temp: 213 degree C and 60 on the bed.50% infill and Honeycombe pattern.I changed the seams to rear , but not sure if all filese are like this, so I advice to slice based on your prefereed settings. For me it have worked fine, but check seams pattern if you want a smooth print.Hardware used:Hinges:M3 x 25 screw x 2 pcsM3 Washers x 4 pcsM3 Lock Nuts x 2 pcsRing Locking I have used M4 x 20 now , awaitng Thumb screws to avoid tools to remove the rig.All other screws used is:M4 x 15 mm for accessories bars x 4 pcs for each bar.M4 x 20 mm for teh Rings mounted on the Vixen BarM4 x 30 mm for the Top Handle 4 pcsThumbscrews M4 from Temu. I have recently upgraded my Ender 3 to 32 bit board, Mini V3 and Touch screen V3All in all the Silk PLA ,Pinrui Fillament purchased through TEMU, have been impressive with no faulty prints.Convenient 250 gr spools.Enjoy , Any donations are highly appreciated.BR.Kenneth.
