Muscle Rack Caster Blocks

Ever wished your Muscle Rack shelving unit could just roll out of the way? I designed these caster mounting blocks specifically for Muscle Rack shelving with the MDF shelves — the kind you grab at the big box stores. These blocks adapt standard caster wheels to fit snugly onto the metal legs of your Muscle Rack, and are designed so the metal legs rest on the caster base itself — not putting all the stress on the printed part. That means a much stronger and more reliable setup! I've tested this with both PLA and PETG — either works may need adjustment if your trying to print in abs or more engineer grade filament never tried. Just a heads up, you may need a rubber mallet to fully seat the legs into the blocks. Included is an assembly guide with the full hardware list, tools needed, and step by step instructions to make the build as smooth as possible. I hope these blocks save someone the headache I had figuring this out! If it helps you out, a like goes a long way in keeping me motivate
