I like MihaiDesigns' idea and the P1P Armor Modplate. This is a remix of Bambu Lab AMS Stacking Stand with Armor Modplate style.
All gaps for assembly are intentionally very small. If it's difficult, please use a tool like a rubber mallet.
Update (Aug. 15, 2023)
All pins are redesigned for better strength. Thanks for the great idea! @djwhouse Now, pins can be printed horizontally.
Update (Mar. 24, 2023)
AMS Stand Rod V2 files replaced with V2-1 (slightly shorter length corrected).
Update (May 14, 2023)
The taller version is uploaded.
Pins are separate parts because they need more strength, so at least 50% infill and 4 wall loops are recommended.
* If you want to push the lower AMS further back, please use Pin4 v2 & Pin4-Spacer instead of Pin3 v2. I will show you the difference with photos soon.
----------------------------------
If you like to keep using the old version stand, I am sorry… you have to glue or drill holes.
You can print AMS Tall Stand Left-1.stl & Right-1.stl files and need to glue them to your existing stand. Using pins by drilling holes is not stable enough.
Also, a new bracing assembly is recommended for rigidity, but you need to drill holes(Dia. 8mm). The distance between holes is 120mm. Please refer to the new modeling parts.
The author remixed this model.
