Your PAL in your electronics laboratory, the Portable Arduino Lab :)
This is a smaller version of the existing workstation for easy small projects on the go!
Compatible with both the Arduino UNO R3 and R4 series microcontroller (possibly also earlier version but I do not own these to verify).
For updates on the project, please scroll to the update section down below.
Newest update on: July 25th 2025, release of ESP32 and Arduino NANO breakout support bracket!

For a larger, more modular but still very travel worthy Arduino companion, click on the image!
Please keep in mind that this is a work in progress! Any feedback, changes or ideas that you have to improve this workstation will be received with open arms! I intend to turn this workstation into something unique and versatile but I cannot do that without your help!
Compatible with the following Bambu printers: X1 series, P1 Series, A1
Printable with or without AMS!
IMPORTANT NOTE:
This models' bracket (microcontroller holder) has been designed using 3 different brand controllers mainly: Arduino, ELEG00 and an unnamed clone. Sticking with the Arduino dimensions meant that the others didn't properly hold. So, I opted to go with a little smaller clearance. That way all controllers fit but unfortunately the genuine Arduino might be a little bit of a tight fit. If this happens DO NOT force the controller in place but perhaps use a small file to remove a small layer of the gripping part.
If you've already printed the first version of the workstation, the bracket and hinge can be reused :)
Instructions
Use profiles included! This insures the hinge from the bracket comes loose without excessive force.
Changing layer thickness may result in fusing and render the print unusable.
ALLOW BUILDPLATES TO COOL!
Removing the models prematurely can cause them to warp and not fit or close properly.
Non Printed hardware required! M3x25 machined screws (2x for model without storage, 7x for model with storage).
Assembly:
STEP 1: Print base plate, hinges and lid as one. Move / Slide the hinges up and down a couple times to ‘release’ them and ensure ease of use. A1 mini users can print parts separately but assembly can be a little finicky.
STEP 2: attach first M3x25 screw into base plate. Model is designed for the screws to be self-tapping.
STEP 3: Hold ‘latch’ in place and insert + attach second M3x25 screw. NOTE; mind the orientation of the latch!
STEP 4: It is highly recommended to use the latch several times to ‘wear down’ the tolerance of the latch ensuring it will be easy to use.
STEP 5: Carefully break free the hinge from the bracket. Mild force may be required!
STEP 6: Snap the bracket + Hinge onto the base plate. MODERATE FORCE IS REQUIRED! Keep the bracket upright and horizontal while snapping in place.
STEP 7: Attach 400 pin breadboard with the included sticky tape or use mounting putty for easier future removal.
STEP 8: Hold bracket upright and insert UNO microcontroller. Secure with M3 screw if needed.
OPTIONAL STEPS:
Print parts of the storage compartment.
Attach storage compartment to base plate with 5x M3x25 screws.
Insert drawer! DONE
Tips
Like most printed objects, any friction will loosen over time. The microcontroller might become easier to remove and place over time.
The UNO can be secured using an M3 screw, but it is not required. The bracket is designed to keep the UNO in place using friction.
For easy coloring of the logo on the lid, go into the slicer settings, select ‘LID’ and change the filament type of the parts highlighted below:
Print Settings (recommended)
No supports needed
0,2mm layer height (needed for clearance between bracket and hinge)
All print in place
AMS requirements is based on your choice!
UPDATE SECTION:
UPDATE (July 25th 2025):
Released a new print profile that contains the ESP32 and Arduino NANO breakout board brackets as well as a bracket to support a mini breadboard for small ‘pinned’ microcontrollers!
NOTE: The new brackets unfortunately do NOT allow the lid to be used. The added height of the microcontrollers gets on the way. I did NOT want to make the lid taller/ deeper as this makes the breadboard sink in as well. Of course you are more then welcome to edit the lid and make it bigger yourself ;)
UPDATE (June 14th 2025):
Uploaded the STEP File for the microcontroller bracket! Create some amazing add/ons for this workstation and share them :) Either upload them as a print profile on this models' page or upload them as a stand-alone. Make sure to link back to this model see people know what is for ;)
UPDATE (June 9th, 2025):
Increased the depth of the logo embossing from 0,25 to 0,4mm to reduce color bleeding.
To those who are interested in using other microcontrollers! Starting with the Arduino NANO and ESP32. The links below are from the breakout boards that will be supporting in the VERY near future:
