I'm curious about your spool holder in the pic. :)
Any details on that?

Awesome design from @Shojo: https://www.thingiverse.com/thing:2041772

Keep in mind to test it with the biggest spools your ever gonna use before screwing it down. I noticed how far it need to come forward for 2.2KG spools. Luckily I did not screw mine down yet. And I plan on making it adjustable in sliding forwards and backwards and easy removable for transport.

Good luck ;)

Hi Thanks for your work. I've printed this out for my enclosure. I have one issue. The top guide's slot seems to small to mate to the bottom guide. Did you have this issue when you printed it?

Hello Whybjorn,

It should fit, but can be a bit snug if your first layer's are a bit wider then the rest.

I left 0,2mm clearance on either side of the mating part (0,4mm total), and 0,4mm Z axis clearance.
0,2mm should be enough for most printers these day's (as far as I know).

Could be its a problem with your first layers. If they are bigger then need to be (also known as elephant foot) this could explain why it doesn't fit for you. Can you check if your first few layers are wider then the rest of the print? Search for "3D elephant foot" for some examples and solutions.

Please let me know if it was an elephant foot issue, or something else. If ya can't find a solution I can upload a version with more clearance on the mating part ;)

Added a picture of current clearances

Do you have a template for what should be cut out of the table?

What length M3 screw did you use to assemble?

Just looked in the 3D file for ya.You might be able to just grab the nut with a 10mm, but I would recommend 12mm or longer.

(I used really long once since I buy all my screws to long. I only buy correct size when I have projects where I need lots of shorter size ;)
