Showing the screen CAN fit an Ender 3.
Select all (because its off screen when it loads)
Move to 0, 0, 0 Its still grey and hanging off the edge.
Rotate, lay flat. This will make it lay straight across the bed, still greyed out.
Next rotate 45 deg. IT FITS!
I have 2mm of brim (max that will fit) because it had bed adhesion issues at the extreme corners.
I am using 0.08 mm layer height for detail. 205 C for stronger bonding of layers. 65C bed first layer to get better adhesion, then drop bed to 50C since long exposure to > 55C deforms the edges. (Temperatures will vary with the PLA used)
DO NOT use .1 mm layer height on Ender 3. Magic numbers are multiples of 0.04 (0.04, 0.08, 0.120....) 0.120 will print faster AND at better quality than 0.10
I have also used Inland brand filament. It is LESS tolerant of keeping the bed above 55C. 65C seems to be the best so far for first layer and 50C after getting good adhesion with the glass and hair spray method.
A added picture of the screen system at 2 panels + tower + 1 tower eliminator.
I am NOT using screws for assembly.
I glued pieces of toothpick in the bottom screw locations for the panels. They drop in the appropriate hole of the dice tower or tower eliminator. Then drop a toothpick (decorate as a flag) in the upper to join the panels to the towers and eliminators.
IT ASSEMBLES IN SECONDS!
The screen panel inserts are MAGNETIC DRY ERASE BOARD faces (both sides now... not shown yet) on heavy card stock.
ANYTHING can be on your screen!
You can change to whatever art you want in seconds. Whatever DM info you want dry erase marked or held up with magnets.
THE ABSOLUTE ULTIMATE DM SCREEN!
Mine is now 4 panels, 2 tower eliminators and my re-scaled tower.
Pictures of that when I have room to set it up for taking photos.
