IMPORTANT IMAGE NOTES: I have no idea why the last (Thingverse generated) one-piece picture looks so rough (or why it has black areas in the middle). The finished item is quite smooth and has uniform color and texture (just as it appears in the other file photos).
This is a (somewhat) fancy top for the beautiful and popular Tudor Box (created by Loubie: Link: https://www.thingiverse.com/thing:408189).
This top adds a railing along the top edge an thus allows you to use the top of the box to store additional items or simply make the top a tad more fancy (but of course no where near as fancy as the sides as I am not anywhere near as good of an artist as Loubie).
There are two versions:
1) A single piece version that will need supports and will involve a fair amount of post-processing cleanup (depending on how easy/clean you supports can be removed).
2) The second version does NOT need supports and must be printed in two parts that are then glued together. No post-processing cleanup is required unless your printer over extrudes (like mine did in the above real-life image), etc.
Please note: The the two halves are VERY fragile until glued together (but one glued the result is quite strong given it's intrinsically fragile appearance).
Worth noting: You can actually print this thing all by itself (without a tudor box) and use it as a holder for a remote control, a few USB flash drives, or other similarly sized odds and ends.
Just print using the same settings as you used for the Tudor Box. Use supports only if printing the one with supports in the filename. Obviously, print large flat side down on all the thing parts.
You may want to use a raft if you build surface is difficult to remove objects off of (assuming a raft would make it easier) since these are fragile pieces (especially the ones that have no supports).
Besides obvious sanding that might be needed for over extrusion, you simply need to glue this to the top of your Tudor box using crazy glue, E6000, or (if you are using wood filament) wood glue.
Note: Crazy glue (aka superglue) generally only works well for PLA if you are gluing wide flat areas together... so it should work well for gluing this top to your Tudor box.... but I have not tried it specifically on mine since I used wood glue.
Any of these glues will be permanent. However, if you wanted a temporary adhesion then a good quality double stick tape should do the trick... just clean both sides thoroughly (and make sure they are dry) before applying the tape.
