FiBo’s are size for 1mm over the box size in tolerance.
My early attempts at using the box were frustrating:
• Uneven spool outside edges
• Spools that bulged in the center
• Spools with wider centers that edges
• Spools that were in between the box sizes
So what I do now is I use one box larger and than the spool size and use an adapter to fit it. Using the low sided adapter I can leave it in the box and put into it “outside-reducers” of the thickness I want to fit my spool. In the end I am giving lots of options… including running -15mm spools in larger boxes.
With the FULL SIZE adapter I and the top bearing sleeve I can fit a box for a spool up to 15mm smaller by adding adapter with 4 more bearings.
*** Do note that the top bearing sleeve requires the top bearings be changed out for 688 bearings… and you will need two zip ties. Print the same part twice. Your bearings must be installed all the way to the stop for the sleeve to fit. You can adjust anything you want in the scad file for tolerances.
With 8 different size FiBo boxes I have printed only 5 boxes through evolution. They are mathematically generated based on size attributes. They have worked when I have changed box sizes, but keep this in mind. Report your success and failures.
The adapters will have about 1.5mm of space material front and back that you can trim to improve fit. Post your notes on what you find works and does not work.
All these parts and options are here for you. I left the fixed sided adapter box that I had originally made in case anyone wants it.
There are a variety of reducers I have generated.
The SCAD source code is posted. If for some reason your boxes are printing tight all the options are in their to make adjustments and re-generate the boxes yourself… if you want. You can print your own adapters and plates of the specifications you want… comments are within the script on changing common settings.

Fibo’s have a very small tolerance of 1mm above their rated interior width.
This module will create one of many adapter options to allow you to use a larger box to run rolls that don’t conform with exact sizing.
For each box size there are options for:
• "fix_sided" // this adapter includes built-in sides and has no slot (has to be removed when using a spool the size of the box) I prefer "low_side_slotted" over this option now, with "reduce_outside"
• "low_side_slotted" //adapter low sides. Print a reducer or outside reducer, has no bearing deck or posts. Does not interfere with spools of the boxes width.
• "fulladapter" // full adapter, low no intefere sidwall, bearing deck and posts printed to be flush to curent bearing.
• "repairadapter" // assumes you will cut off your current lower posts. Prints a low wall box, slots for 0-5 card. longer bearing posts, bearings should be 1mm off wall.
• "reducer" //Standard reversable reducer plate
• "reducer_outside" //This is the spacer that goes to the outside wall. This would be the most common to go 5mm down. It fits the slotted box only and full bearing dolly.
There is a setting at the top that controls the what gets trimmed off your reducer cards. Make sure you read the note about double sided card trims.
addclearenceforspool = .75 ; // half will be deducted from each reducer card generated
