ProtoRoller (3D Printed Disc Golf Cart)

This is the 3D printed disc golf cart for anyone that has already spent all their money on printers and filament and finds the cost of commercial carts too much. I call it the ProtoRoller! (Thanks Tyler).

After throwing a round on one of the local courses, whilst lugging my bag around, I saw they had Zuca carts for sale. Out of curiosity I checked how much they were and was surprised at the cost. Figuring I could make one for cheaper I turned to my favorite medium of creation and thought, “I can 3D print that”.

So here we are.

Aside from the luggage handle, fasteners, wheel bearings, axel, and shaft collars everything is 3D printed on this cart.

This model uses between 2 to 3 rolls of filament, 67 bolts , 61 square nuts, 6 nuts, 9 washers and 2 shaft collars.

Everything is designed to fit on a 256mm cubed build plate with almost none of the pieces requiring supports aside from the rims and tires.

I used the ".20mm Standard" layer height profile with an increase of walls to 3 for all the body parts and the “.20mm Strength” profile for all the black parts and the drink carrier.

I printed the whole cart body, fenders, and front guards, and drink carrier in PETG HF from Bambu

The rims are printed with the shiniest silver I could find which was silver PLA+ from Bambu

The tires are printed with TPU95A also from Bambu.

I got all my hardware off https://boltdepot.com/Catalog-Tabs?gad_source=1&gclid=Cj0KCQjwoZbBBhDCARIsAOqMEZVtifNozADGwqqzJGDlakFSJCU6p90gjZv7d_ewtp5NkuUVBztkrtkaAr4bEALw_wcB They seemed to have the best prices that I found.

Hardware:

     M6 hardware is used to attach the luggage handle and the front feet.

6 - M6x40mm

6 - M6 Nuts

6 - M6 Washers

     M5x25 is used to attach the bottom pieces together, the bottom pieces to attach to the back and the back pieces to attach to each other.

31 - M5x25mm

     M5x16 is used to attach the 2 piece rims together and to attach the fenders to the bottom and back which also doubles them as gussets for stiffness.

24 - M5x16mm

     M5x8 is used to attach the front guard to the front of the cart.

6 - M5x8mm

All M5 hardware fastens into M5 square nuts. MAKE SURE YOU GET THE 2MM THICK SQUARE NUTS https://amzn.to/3YLZji8 

For bearings I used 6200 bearings https://amzn.to/4kjbJ9n off amazon and they are a tight fit in the rims. I lightly hammered them in.

I used this luggage handle. https://amzn.to/44yRsrU this same handle is sold by several different suppliers so if it looks the same as the one in the pic, it will most likely work.

600mm of 10mm linear rod for axel. You'll probably want to trim it down. My axels ended up being about 560mm https://amzn.to/4jTqCPV This link has 2 rods in it but then you can just make a second ProtoRoller!

There are also 2" spaced holes on the tops to add 2" U-Bolts if you want to add a place to clip in your things like keys if you want them out of your pockets while you play your round or have a towel with a clip on it for easy access.

This has been a bunch of fun to design despite me still being an amature designer. this has been through many iterations with new ideas popping up while designing along with input from friends. Some said I should make this a paid model but I've seen people post a lot more impressive models for free so in good conscience I cant do that.

I have had this cart along with me for about 4 rounds already and it has held up wonderfully. I hope if anyone prints this it serves them well. Go get that ACE
