Cheap and Easy Voltage Regulator - FrontThis is a quick and easy build that almost anyone should find  very satisfying with a budget of less than $10. It uses a 35 Volt 5 Amp DC - DC Boost Converter that takes in anywhere  between 4.5V – 30V and boosts it to almost 36 volts. Combined that with the inexpensive and popular 100V 10A Voltmeter / Ammeter. Connect everything together with some proper gauge wires connected to a couple pairs of male and female banana plugs for easy connecting and disconnecting of various devices, wires, and clips.

Quick, Easy, and Cheap 36 Volt 10 Amp Power Supply - RenderI took all of those parts and modeled each of their dimensions separately in Autodesk Fusion 360. Once all the different components were modeled I spaced everything out in the best possible orientation I could find, while making the most compact design.  After making sure that there were small channels in the model to account for the wiring I made a case around all of it. If you are interested in printing this case yourself I have uploaded the complete model on Thingiverse.

CR-10 Mini X-Axis Belt Centering Spacer

CR-10 Mini Belt Centering Spacer The first mod I created for my CR-10 Mini was a X-Axis Belt Centering Spacer. While assembling my new 3D Printer I noticed that the belt that controls the x axis which moves the extruder left to right was not running down the center of the extruded aluminum chassis as intended by the manufacturer. After searching high and low for a solution the ones I found were for tensioning the belt and also center at the same time. This seemed a bit overkill to me as the belt is very easy to tension, all I needed was a spacer to offset the idler pulley. You can see the blue spacer in the picture.

To get the proper size for your spacer you will need to measure the gap between the belt and the frame inside the channel, mine was 1mm. The spacer is 2.5mm thick to allow for some squishing to get good bed adhesion for some. After the 1 minute print finishes measure the thickness of the spacer and if it is too thick. Open your slicing software and simply cut off bottom of model  as necessary.
