3D Basecamp Design Challenge


We were so impressed with the last challenge results, we just couldn’t wait to do another. So instead of putting it off any longer, let’s get the ball rolling! This next challenge is a little different than the last (and the winner gets a free ticket to 3D Basecamp!) so read on for more details :slight_smile:

This year’s 3D Basecamp is right around the corner and you could say that our planning is in full swing (pun intended). For this challenge, we’re asking you to model a fully constructible mini golf hole that stays in theme with this year’s 3D Basecamp in Palm Springs. Think flamingos, golf carts, palm trees, and all things retro. This challenge is sponsored by ShopBot and they’ll be using their CNC machines to cut and construct the winning models, so make sure your model is something that can actually be built and played on. Also, feel free to get creative! CNCs do some incredible things :slight_smile:

Building requirements:

  • Final designs must fit in a 5’ x 10’ footprint
  • Designs must be cut from no more than two sheets of ½ inch 4’ x 8’ plywood and four 8’ 2x4s
  • The design must include a 4” hole
  • Templates and examples can be found on 3D Warehouse
  • Feel free to spruce up your model with fun elements (trees, etc.) to give us a look into what the final design would be (we can add those after it’s constructed)
  • As an FYI, we won’t be using standard golf balls for this course (too many concerns about golf balls flying through the halls). We’ll be using ~3" foam stress balls. Please make sure the design takes this into account.

Details and prizes:

  • The model(s) must be completed and uploaded to 3D Warehouse by May 18, 2018
  • Winner will be contacted at the email address listed on your 3D Warehouse account
  • Judging is based on constructibility AND creativity. The first round of judging will be done by the SketchUp Knowledge team, and the final round will be done by YOU! Stay tuned for the online poll after May 21, 2018.
  • Grand prize includes one free registration to 3D Basecamp 2018 in Palm Springs, California (flight and accommodations not included) and your winning model used in the 3D Basecamp putt putt course. No alternate prizes available.
  • The five runners-up will have their models built for the 3D Basecamp 2018 putt putt course. Creators will be given full credit for their designs!
  • You must add your model(s) to 3D Warehouse and tag it with the hashtag #CNCGolf to be considered

Please note that if you’ve already purchased a ticket to Basecamp, you’re still welcome to participate! We’ll happily refund your ticket order if you win :wink:


Can the 2x4’s be “ripped” along their length or must they remain 2x4 (1.5” x 3.5”)



That’s ok… within reason. If you end up cutting every single piece into ½” strips… we may ask you to do the cutting for us.


Question: what if one happens to win the challenge and already purchased a ticket to basecamp?



You’d better be coming either way.


I’ll be there! All booked!


10-4…it’s a deal…thanks

One more question…and hopefully my last…can 3/8” plywood wiggle board be used in place of 1 sheet of 1/2” plywood?



That IS a limitation of the design. All flat pieces will be milled from 1/2" material!


Can you use concrete blocks to create raised platforms?


Nope! The only materials that can be used are the plywood sheets and the 2x4s!


Thank you Sir


Are we using wood screws, nails, or something else? Is astroturf going to be the top layer or do we have other options? For example, a carpet or fabric with a pattern:

Can we use paint? If so, is there a limit on the level of detail to the art? Does the hole have to be a certain height to allow the ball? Are we allowed to use a plastic hole insert?

This challenge is really fun. I made a banked hole:

And a halfpipe hole (you have to catch some air to make it):


I had a good look at the #CNCGolf Example #1, just in case I want to give it a go.
Was this (selected group, 2x4 at the top end of the playing field in the example) done deliberately or was it just a case of bad milling :upside_down_face:
(The red line is where there’s a stray edge left. And measuring between various endpoints (and ‘On Face’ along axes shows a skew piece of wood, here one is marked yellow as an example)


Does the cnc machine only cut all the way through the plywood or can I route a line in the wood at a certain depth for instance? Just a buildability question. Thanks!


@kyleatx You CAN mill to different depths!


@Forestr , We will be placing astroturf or folt on all designs (it will be the same for all holes). Also, yes, we will be using some sort of screw to hold them all together. All you have to do is come up with a design where pieces connect, but no need to define screw placement, or anything.
