Bearing Spool Holder with Adjustable Platform

The spool holders that use bearings seem the most robust of all spool holders to me, but I've grown tired of knocking them over accidentally when I change filament. This platform helps keep them stable. It is adjustable to most common spool sizes for 1.75mm filament.

You may not need the 3/8" #4 wood screws that keep the bearing holders together, because the bearings should fit quite snugly. You will need 4 common skate wheel bearings for each spool holder set. You may be able to print your own:

I normally print all parts at .12-.18mm. Smaller parts should be printed at highest quality (.1-.12mm). Supports should only be needed for the two inner spacer shelves of the platform.

The following quantities are needed for a single spool holder set:

Bearing_Holder_half - 4

platform - 1

support - 2

small nut and bolt - 2

Notes:

The small bolts with the finger nut can be a little stubborn, but my printer may need calibration. My first try for the printable bearing was abject failure, so I guess I have a printer fine tuning project ahead of me. Luckily those 608 bearings have pretty well flooded the market (I always have a few spares on hand for my RipStik wheels).

How I Designed This ===================

Lots of boolean subtraction

I used Cheetah 3D and boolean subtraction to get the supports (rectangular prism with trimmed corners and a hole) just right.
