A reusable spool for filaments that come with inner diameters that are smaller than usual (75mm). Compatible with Bambu Lab AMS!
Background
I recently discovered Kinluot filament (thanks All3DP!) and I've been shocked at how great my prints have come out considering the price per kg. I tried a few different solutions for my Bambu Lab AMS since Kinluot spools are cardboard, but I kept having issues with them one way or another.
I found @chiz's excellent models for Customizable AMS Spool and Parametric Bambu Lab Spool Adapter & Spacer and thought those would do the job, but I didn't realize until after I had ripped one side off a spool just how small the opening's diameter was by comparison (standard Bambu Lab reusable spools have an inner diameter of ~80mm).
If the threads look familiar, it might be because I drew inspiration from @humebeam's Silica Gel Holder.
Recommended Print Settings
- Supports: None. If your threads turn out poorly or need a lot of post-processing, you could try changing your order to infill/inner/outer
- Material: My first print is in Inland PLA+ and it seems plenty strong. Once it has had some mileage, if I notice some strength issues, I'll update here. PETG is always a safe bet
- Layer height: 0.2mm with 0.4mm nozzle
- Wall loops: 4
- Top/bottom layers: 4
- Infill: I set mine to 15% with the Gyroid pattern
When installing, make sure you do the following:
- Before beginning, secure the end of the filament somehow
- Only remove one side of the spool at a time
- If you can see the notch(es) of the innermost cardboard piece, try to start with the side that has a notch that isn't being used by the spool to hold the end of the filament.
- Make sure to insert the outer side printed part first (the shorter of the two halves) and align the tab with the notch in the cardboard
- Carefully turn the spool over, remove the second cardboard side, and screw in the inner side printed part until it is giving the cardboard piece a nice, secure squeeze
