Bambulab spool holder adapter for 3030 extrusion (RatRig)

Spool holders using PTFE tubes were chewed up by cardboard spools after some time and I had an all metal bambulab spool holder lying around… 

(For RatRig V-Core 4 owners : the adapter width + the length of the Bambulab spool holder stills clear the bed, so it's fully compatible with the original spool holder location)  

Print instructions:

• no supports
• part already oriented in .stl (flat side down)
• standards RatRig print settings : 4x walls, 0.2 layer height, 25% infill
• material : if enclosed, preferably ABS or ASA

BOM:

• 1x adapter (printed part)
• 1x Bambulab spool holder
• 2x m3 Inserts (5,7 x 3 x 4,6 mm preferably, but with enough heat, any m3 insert size should fit :D)
