Previewing .STL Files in Windows Explorer

So you have been into 3d printing for a while and have a giant collection of 1000’s of .stl files saved on your computer and you have no way of easily viewing previews. Looking for a way to be able to view your files as soon as you open up your STL folder?

Here’s a program developed by cabbagecreek way to be able to preview a thumbnail of your stereolithography files.

From the website:


Marlin3dPrinterTool is a open-source software that helps you configure and test your 3D printer. The software contains some components that are not free and leave some demo and watermarks. The Software is ditributed with “beerware license” as in “free as in beer” and all donations will be used to pay for the components.
The software is under development and some features ar not fully tested on all types of 3D printers. The code is tested on:

– BigBox Pro
-Rigidbot Big
-RapideLite 200

The main features are:
-Endstop testing
-Bed limit and bed abjusters position
– Z-probe configuration
– Bed Level Tool
-Scan building surface and create visual chart
-Z-rod maintenance
-Auto PID calibration
– Extruder calibration
-Firmware upgrade and migration
-STL thumbnails in Windows File Explorer

5. Click on install and register STL thumbnail

You might have to restart File explorer on you are done, the configurator allows you to do it automatically.

You also have the option to set the viewer as default and to change the STL preview color .

Printer bed leveling

Having a level build platform is crucial to successful prints. This allows the first layer to be applied evenly and properly adhere to the build plate. having the nozzle too far from the build plate can cause the print to warp or even dislodge while printing. If your nozzle is too close to the build surface, the filament will be squished against the bed and this could either jam the extruder nozzle or complicate the print removal process.

First off; when leveling the build platform you will have to heat the bed to it’s printing temperature. The thickness of an aluminum bed will vary greatly depending at what temperature it is in. To level your bed properly, the same temperature at the time of printing is needed.

Place a sheet of paper on the platform, you will want the nozzle to touch the paper and still be able to move it freely with a bit of drag.

Move the extruder to each corner of the platform making sure that the amount of drag is constant on each corner, adjust the screws on the corners accordingly.


The center part of the build plate is the most important to have leveled properly as this is the location where you will most often be printing at.

Make sure to double check all positions once you are done leveling all four corners.

Perform this routine every time a physical parameter is changed on the printer, or if the printer is moved to another location. Once you get the hang of it, it will be very quick to level and you will not need to resort to any auto calibration features on your printer.

Spool Holder with spare parts


Here’s a quick DIY spool holder from leftover printer parts. I understand that you might not already have these parts on hand if this is not the case hope you can get inspired by this and create something similar. The criteria for this mini build was to use parts available on hand and to have a solid one piece spool holder. (Although I had to order proper length bolts for the v slot wheels)

Total build price: Under 25$

What you’ll need:

2x 2040 Extrusion cut to 230 mm
1x 2040 Extrusion cut to 70mm
4 x V slot wheels or 625zz bearings
12 x 5mm T nuts
4 x 5mm x 15mm hex bolts
8 x 5mm x 8mm hex bolts
4 x Extrusion corner brackets (STL)
4 x 5mm washers
4 x 2040 Endcaps (STL)
