Description
This is my large designed using Fusion360 on a printed hinge. This will occupied your whole Ender 3V2 bed size. Ensure very good bed leveling.
No support needed as all latches and protrusion are designed at 45degree. For those with 90degree from vertical print, I added small and thin 45 degree wedge support in the print model. You can remove it with a sharp cutter . All holes are printed without support.
Ensure your 3D print can print bridging at least 10-15cm apart without bridging or stringing.
Do not rescale smaller than 80% as will affect hinge tolerances.
The final STL published has all the flaw fixed. Since my 1st print is still useable I didnot reprint the latest STL. Welcome to try and inform me..
Printing:
Print without Support.
Printing time ~ 14-15hours, using about 100g spools.
You can add your own embossed initial inside the box.
The published STL do not have any initial.
If the 3D print hinge fails for whatever reason, do not force as this will break the side wall. Use a hot blade and cut all the hinge pins. Then drill a 2mm hole to 3 hinge support and added a 2mm metal wire as pin hinge support .
Welcome to remix or use it.
This is my first large and > 12hrs print that I designed.
I added my 1st version of Cura slicer on the hinge. Welcome to take a look and compare if your slicer is similar to mind, then you will have a stuck hinge due to too close tolerance for the filament and no gap.
The STL for top and bottom are separated and you can adjust the gap.
Just print 3 Gear and the latch slots.
Printer Brand:
Creality
Printer:
Ender 3
Rafts:
No
Supports:
No
Resolution:
0.2mm
Infill:
30
Filament: PLA PLA Blue
Notes:
Do not re scale smaller than 80% else the 3D print hinge will fused together. Require a precise 3D print. This will print at full bed size from Creality Ender 3V2.
My first version having hinge printed and fused together that I have to remove the pins with a hot knife and added a metal slot as hinge replacement.
For the combination lock , i added M1 screws to secure inside the box.
The safe box that I printed for myself has initial, however I remove the initial in the STL files. You are welcome to add your own embossed initial.
If you bed is not big, then print separately Top and Bottom STL. Then remove the hinge pins and make a hole for a metal pin.
The whole safe box is printed one shot at 80% rescale.
My 1st print having tolerance issue with some layer having fused or stuck hinge. Most of the gaps are ok. Only the center pin is too close. I change the published STL file later on with > 0.5mm tolerance.
1st layer print. This print really test your bed levelling flatness!! Ensure very good bed leveling. Beginning of a 14hours print
This is my 1st version of Hinge gap tolerance issue. Too near at 0.1mm.. However I fixed in on the published STL version with 0.5mm
The Published STL has a better gap about 0.5mm for the hinge pin as clearly show in the Cura Slicer. If you successfully print this in 1 print with a working hinge. Do let me know!
