Printed model for the rondix 35 New version ; pictures are from an older version. WARNING ! Not Printed ! Not Tested !! Warning !! This one improve the inside of the tank (tighter tolerences and ridges for preventing film scratching). The "joint" part and the axle are now using a screw to fit thightly together. It use a M4 nut and a M4 screw. The joint is designed for a 16.9x22.3x2.7 O-ring. Another seal will be need at the screw head (haven't figured which one to use, perhaps this one http://www.leroymerlin.fr/v3/p/produits/5-clapets-perces-4-x-17-x-5-mm-ideal-standard-n-81-e5925) I haven't tested if it leaks or not ! And ...please visit this awesome website https://rondinax.wordpress.com/ which has a lot of information on rondix&rondinax ! The guy helped me a lot ! Most print should be rotated before printing ... altough I do not recommend printing yet ;)
