Twenty minutes of golf on the table. The course is built from printed hex tiles during the game, and you flick a 45 mm disc with one finger.
The course is made of printed hexagons that lock together. It gets built during the game, so every hole is different. Felt slows the disc down and a bumper sends it back. A slow disc that rolls into a water hollow stays there. Every player holds one secret tile and may swap it into the course once per hole, and my 6-year-old daughter takes one stroke off every hole. There are no electronics and no AI in this one, so it also works during a power cut.
The mat goes on the table, and the tee and the hole go on the mat four tiles apart. Everyone gets a secret tile and keeps it out of sight. The first tile out of the bag is already part of hole one.
You play against Daughter (6), whose shots are simulated with a deliberately shaky aim. You take turns drawing tiles until the tee and the hole connect, and then both of you flick. She has a secret tile as well, and she uses it.
Hole 1/9
Your turn to build. Draw a tile from the bag.
| Hole | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | Total |

The physics is a rough model made up for this page. Real felt and real PLA will behave differently, and that is one of the things the first prototype is for.
A disc creeps toward the hole, everyone leans over the table, and it drops through into the drawer with a clack. The hole tile is built around that moment. It only takes a slow disc, so a hard flick rolls right over it.
Sample scene, made up for this page. Hole seven. I’m one soft flick from the hole. My 6-year-old daughter has kept her secret tile since the first shot, and now she snaps it in right in front of my disc. It’s a water hollow. My disc now has to be fast enough to cross the water and slow enough to drop into the hole on the far side.

This toy has no AI and no electronics, so this section belongs to the printer. About 30 tiles that lock together in any rotation turn one bag into a new course every hole.
Each obstacle is its own tile: felt, a water hollow, a hill, a bumper. The tiles print with the colored face down on the bed, so the top comes out flat and the seams stay smooth for a sliding disc. The 45 mm discs have a steel washer printed inside, and the hole tile has a drawer underneath to catch them.
The MMU3 handles up to five colors, and the waste from color changes is part of why the estimate is about 2 kg of PLA for thirty tiles.
Not printed: the anti-slip mat, the felt, a bag and score cards.
None. There is nothing to solder or charge.
Everything fits the MK4S with the MMU3, and PLA is enough. Nothing in the set needs a flexible material.
| Item | Amount | Price |
|---|---|---|
| PLA for the tiles, the hole tile and the discs, including waste from color changes | about 2 kg | most of the total |
| Felt, steel washers, anti-slip mat, bag, score cards | one set | the rest |
| Total | 900–1,600 CZK (about €35–65) | |
The estimate covers the whole set. Most of it is filament, so the price moves mainly with the PLA you buy.
One hole is a loop, and the whole game state sits on the table: the tiles in the path, the discs, and the pencil marks on the score card.
Nothing here runs code.
Nobody asks a model anything, not even who won.

Each player gets three discs that work like clubs: a slick one for long shots, a regular one, and a felt one that stops almost where it lands. You call the disc before the shot, and the water hollow turns into a real golf decision. You can go over it or stop safely in front.
Everyone gets a handicap card with their average strokes over par from the last three games, and the lowest score after the handicap wins. Par comes from each path, so it stays fair on a different course every time. My 6-year-old daughter’s fixed stroke off becomes her own number, and it drops as she gets better.
Instead of drawing random tiles, one player builds each hole for the others, and builders take turns. The builder plays last, takes a stroke off for every opponent who misses par and adds two strokes for missing par on their own hole. The secret tile goes away, because the whole hole is now the trap.
Real putting across the living room with golf balls, kids’ putters with PETG heads on wooden sticks and bumpers from wooden strips with printed connectors. Each hole is designed by one of the kids and gets a name, its author’s rule and a record in a logbook. Whoever finishes last draws a new obstacle for me to print, and the course grows up to eighteen holes.
Status: an idea. Nothing on this page has been built or tested yet, and the demo is a simulation with pre-written answers. Prices are estimates from Czech shops in October 2026.
