thingiverse
A Simple and Budget-Friendly 3D Printer Assembly. Designed to be assembled with printed components and standard 1-inch square aluminum tubing commonly found at most hardware stores. The original source for the square tubing is Home Depot. https://www.homedepot.com/p/Everbilt-1-in-x-96-in-Aluminum-Square-Tube-with-1-20-in-Thick-802537/204273939 The Prusa Mk2 hotbed is suggested as a perfect fit, given its design will complement the build dimension. Aftermarket stepper kits are also available and fit perfectly. https://www.aliexpress.com/item/Reprap-Prusa-i3-MK2-MK2S-3d-printer-42-stepper-motor-320m-L-Z-Motor-with-Trapezoidal/32841178172.html You may find a more affordable stepper kit in your local area, or one that uses couplers instead of direct connect lead screws for the Z axis.
