Bartop Build v2 (with coin mech, hopper and topper)

I hit a snag on my first bartop build in that I didn't leave enough room for a coin hopper. 😑 So I decided to start again from scratch and this time I took the time to model it up in Sketchup first to make sure everything would fit. I still wanted it to be as small as possible but to also fit a coin hopper and coin mech and a bigger screen (27in instead of 24in). I also recently bought a 3D printer so I wanted to utilise that in the build too!

So fast forward a few months and here is the end result:

This is all made out of 18mm mdf (and it is very heavy!) along with some custom 3d parts I made. It has a 27inch touch screen, Suzo Happ Cube Hopper MKII, Barcrest coin bezel with custom 3D printed mount plate and coin slide. I also added a real slots topper, the insides I replaced with an ESP32 running WLED with 5050 RGB LED's.

The buttons are from Ali Express and I replaced the (Loud!) switches with some quieter Cherry switches I had lying around. The graphics for the buttons were courtesy of ChatGPT and I just printed them on normal paper. I might redo them at some point but for now they are good enough. 

I added an LED strip to Illuminate the coin tray blue and also added a hidden button that will trigger the hopper to pay out some coins to play with. The coin tray itself is a stainless steel loaf tin! It's a fraction too big in hindsight so it's really squeezed in there tight but it works. 

I 3D printed a volume control bezel to make it easier to mount the little amp (PAM8403) to the 18mm mdf and I printed some Wago connector mounts for the inside to help with cable management. Here is a view from the inside:

Quite a spaghetti in there, even with some cable management going on!

The PC inside is a Ryzen 5 3500x, 8GB ram and a GTX 950 which seems to be more than enough for what I need. Everything runs off the pc power supply too as its all either 12v or 5v which can all be taken from a molex connector. 

Overall I'm really happy with how it turned out and it definitely paid to spend some time 3D modelling it all first. Everything fitted together pretty much as expected with very little tolerance (I dont think it could be any smaller with a working coin mech and hopper installed!). 

Happy to share my Sketchup file for the build and the various 3D print files etc if anyone was interested.  Here is a video of it in action:

 

All the best, 

Steve

That looks really good. What front end are you using?

Thanks, I am using Coinops for the frontend with a vertical theme applied. I've uploaded it to the link below if you'd be interested. You'd just need to add your roms, videos and logos:

This looks fantastic, great job. I’d love to see the SketchUp file for my own project - if you wouldn’t mind sharing?

Apologies I thought I'd already shared it but here it is:

Im pretty new to 3D modelling so hopefully this gives you what you need! I have since moved to Fusion instead of Sketchup but I don't have it modelled in Fusion, only Sketchup.

Ah no worries. Yeah, it looks like you can export it to DXF in Sketchup if on paid sub, but I don't have a sub, was only looking at your model through the free version.

Ah right. I am also using the free version. There might be an online tool or something though perhaps?

Yeah I am looking for a front end for my cabinet thanks for the link I will give it a try.
