Buttercade Top Loader for Hori Real Arcade Pro

With the top loader on the handle, position the loader to the open screw hole on the HRAP case's plastic underside.  The goal here is to get a clear an opening as possible that should line up relatively close to the plexi and artwork's own screw holes, which you will install later. One way to accomplish this is to place the plastic case on an open surface where you can easily see the original screw hole through the loader.  You can also place the case upright to see through the front of the case's square-shaped screw hole as you place the loader in the back.

Lightly apply pressure to the loader using the top of the handle between your thumb and forefinger, with the intent to check the spacing of the loader before committing to its final position.  If you find that the loader is off position (the top loader's screw hole is clearly offset from the center of the case's square hole), you can attempt to pull the loader out, replace on the handle and try again.

Once you have the screw hole on the top loader relatively centered with the square hole of the case, apply as much downward pressure to the handle as you can to secure the top loader's adhesive to the plastic.

We offer M4 hex screws in several colors to customize your HRAP 3 artwork or plexi install.  The screw uses a 2.5mm kex key.  It is important to note that the original HRAP 3 screw was designed to fit into the square hole. Additionally, the HRAP 3 was not designed to accomodate custom plexi. This means that the artwork and plexi may shift around until you secure it with the screw. Position the artwork so that it lines up with the edges of the metal panel, and centered around the buttons.  That may require you to grip your fingers between the plexi and artwork and move around until all positions look correct, then screw down.

When installing the screws, please screw down lightly at first so you can make any corrections to the artwork and plexi position. Do not force the screw in hard, as the this does not allow the screw to catch the top loader's threading and may dislodge it.  Instead use the hex key to screw into the top loader's opening.  It should tighten once the threading catches.  Occasionally a small piece of the 3D printed plastic may obstruct the metal screw nut.  You can use a small pointed tool to clear that debris from the opening.

Finally, when screwing in to secure the artwork, you should feel the screw tightening around the top loader's metal nut.  This will improve the adhesive bond. Do not tighten too much for risk of cracking the acrylic, especially should you choose the thicker and less flexible .060" plexi. Tightening too hard will also cause the thinner .030" to bow around the back and around the control panel, where the acrylic's surface area is narrower.
