Finally have the full suite of mods installed on my machine.
Smooth Rolling Film Pulleys
I did the pulley mod, I already had some random slippery maybe nylon spacers in ~24mm length so I just cut them in half to about 10mm spacers when I was done.
The washers were 3D printed in 0.5mm increments up to 5mm. [Attached to this post.] I used a 0.5mm washer on the outside, then the spacer, and finally whatever sized washer on the inside to mostly fill the shaft to the shoulder, but not quite, to ensure free rolling.
The hardest part is holding this all to put the screw back in on the backside. So, I also made a custom 1/4" drive or 1/2" hex socket handheld tool to hold the posts steady for me. [Attached to this post.]
SD Card Relocation
As I had briefly alluded to last month I was working on a relocation kit for the SD card. That is now complete.
On the back half of the unit I placed the existing SD card slot enlargement template.
Drill the holes, trace and cut the slot.
Two #4 x 1/2" sheet metal pan head screws secures the new cover.
Locate a good spot on the front for the new SD slot:
Drill and cut.
Mount the SD slot to the mounting board with M1.7 screws.
Using #4 or similar screws, run them through the faceplate and body pulling in the SD card holder. Note in this final design the metal SD card slot will sit more flush with the face of the existing Reels housing instead of being more inset.
And we're done.
Note that this SD card relocation uses updated files. I have added those to my original
post for the SD relocation.
