About this 3D model

I've used the Spool Roller by thrutheframe for quite a while until in noticed, that some of the spools on the market won't fit - most popular the Prusament spools, which you need to force on the roller until the front tab breaks off - some others wont fit at all so i took idea to use to original metal holder and created a spool roller that fits inside this space Single Body + 2 interchangeable Rollers they can be swapped quickly without disassembling holde Type A: is self centering and can be used for wider spools Type B: has notches to keep narrower spools centered if you are not sure which one is right for you: the Type A is perfectly fine - only almost empty cardboard spools with little weight tend to slide around - here the Type B is more sturdy BOM 2 x regular 608 ball bearings 8x22x7 mm 1 x the stock spool holder from the P1P/X1/X1C compatibility basically every spool holder that utilizes the stock spool holder also fits the the Side Spool Arm for the P1P printing the body can either be printed upright with traditional supports or at a 45° angle with the back side (indicated by an arrow) on the buildplate with additionally painted supports - filament does not really matter, they are sturdy enough - just don't use silk filaments, to be safe use a ductile filament like PETG the rollers should be printed upright with concentric top and bottom patterns and a traditional support at the base - pick a random seam position, so it looks a bit nicer - you only need to print one roller - if you are not sure, just print Type A assembly flip the original spool holder upside down and just gently press the spool roller body into the metal frame - the arrow on the underside indicates the side with the screws facing the printers body apply the bearings to the roller (they are supposed to have a snug fit and not fall off - you can blast the ends with a torch and press them on warm, so the fit snuggly) then just insert the roller into the body: done special thank you to MOOO for the Original Bambu Lab P1P Filamentholder model, which saved me some time here :)
