compact mod of the ERCP

• combine spoolholder and buffer into a really small and dense package
• can be hung from the ceiling or placed on a level surface
• make spool changing fast and easy
• look cool
• Buffer length per winding: ca 400mm

Note:

• the buffer wheels and buffer 608 adapters are the same as in the original design!

General:

• M5 threaded rod for the buffers (20mm + amount of buffers*20mm)
• M5 nuts
• M5 Flat head screws for the ends of the extrusions
• 2020 extrusion (this is designed for 5mm slot width but should work with 6mm as well)

per spoolholder+buffer combo:

• 5x 608 bearing
• M3x12 screws
• M3x5x4 threaded inserts
• ECAS04
• 4mm OD/3mm ID PTFE tubing (dont use the clear stuffas its FEP)
• about 200g of filament

• cut M5 threads into extrusion ends
• install threaded inserts into the buffer frames
• press in ECAS04
• press in Spoolholder 608 adapter
• press the buffer wheel assembly together
• put it together!

• the wheels should spin freely
• the bearings should spin freely
• the PTFE tubes should make nice slow bends as to not cause friction. I recommend feeling every tube by hand to get it right.
