Spool Roller / Holder for Bambu Lab P1P/P1S/X1/X1C

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
