RobotDigg Spool holder with 608ZZ skate bearing inserts
Description
I Could Not Find Anything On Thingiverse That Fit My Robotdigg Pla Spools So I Made This 4 Mm Thick Spool Holder, Quick Print. With A Small Mod You Could Adapt It To Fit Any 200 Mm Diameter Spools. Fits 21.93 Mm Diameter Skate Bearings, Nice Friction Fit With A Taper At The Back To Keep The Bearing From Being Pushed Into The Spool. The Robot Digg Spools Have A 38.14 Mm Diameter Hole. 104 Mm From Center To Base So Fits The 200 Mm Diameter Robot Digg Spool. The Cross Members Are A Tight Fit So Tapping Them On With A Small Hammer And A Drop Of Crazy Glue Makes A Nice Strong Connection. Leave The Little Bag Of Desiccant In The Spool So It Doesn'T Back Spool, The Bearings Are Very Smooth. I'M Using A 6.26 Mm Bolt In The Pic But It Is Sized For 7.75 Mm Threaded Rod.
