Richrap Masterspool for Bambulab Adapter (Light)

A lightweight adapter to fit Richrap Masterspool-Refills on the Bambulab-Spool.

It only weights 80g in PETG and prints in ~3h (~2h with 0,6mm nozzle)! Less material than completely printed spool, but you must have a Bambulab-Spool. 

Drying the filament shouldn't be a problem, because it is as open as it can get (if printed in PETG or ABS/ASA).

Compatible with both AMS and AMS-Lite (it is the Bambulab-spool after all).

Works with 800g refills from DasFilament and it should work with 850g refills from Fiberlogy (not tested). Any other brand that uses the Masterspool by Richrap “standard” should work just fine

Notes: 

• I am not 100% done with testing this adapter. It prints and it holds the full spool. When locked, it holds the filament and prevents it from rotating inside the spool. I have not tested the behavior when its half- or 1/4 full. It should behave the same as any other Masterspool print, but I have not confirmed it yet.

Instruction:

1. Print both parts (I recommend PETG or ABS)
2. Place bigger part (A) on the Bambulab Spool with the notch
3. Place your refill with the inner end up
4. Secure the inner end at the cutout (triangle) using the holes (second last picture)
5. Press the smaller part (B) onto the bigger part (A). The cutouts for the zip-ties must line-up. It should lock into place.
6. Use the other Bambulab-Spool half to close everything. You need to slightly press it down
7. You can either use the holes from the Bambulab-Spool or from the printed part to secure the outer end of the spool.
8. Cut the zip-ties and start printing.

Material:

• PETG is recommended because it is easy to print and should withstand the heat used to dry filaments like PLA and PETG. (~78g)
• ABS works pretty well and allows higher temp for drying (ABS for example). (~65g)
• PLA can be used if you don't plan to dry the filament (~81g)
