Makerkar – Library Makercart – INSTRUCTABLE

The MAKERKAR in constructed out of 30x30 extruded aluminum profiles. Bolted together with external corner connectors.
Internal corner connectors, which will be invisible, makes you  less flexible if you want to modify things.


  • Allen key 5 mm for external corners
  • Allen key 3 mm for internal corners
  • square
  • tape measure

Building the frame requires no welding, drilling or gluing, just bolting.

Makerkar alu frame

The secret of building the cart is to assemble the bottom frame on an absolutely flat floor. Then build up, using a square. Mount the wheels only when the entire frame is built.

Makerkar carrier frame

Construction is quite straightforward: start with the bottom frame on a flat floor. Two beams and 6 girders. The ones for the wheels sh0uld probably be 80 mm apart. Just check with a wheel, that will be bolted later on.

Now add 4 risers in the corners. Feels wobbly, but will become solid.

Construct the lower shelf (the box for the Cameo will be added later); Free space to the bottom shelf is 58 cms
Check with ruler and square.

Construct the upper shelf, free space to the lower shelf is 14 cms
Add the top, except the front bar, which will be removable for access.
Free space to the upper shelf should be 28,5 cms <check the math :)>

Now add the Cameo box.
<new photo required as it is longer for the vinyl tube now>
Turn the frame on a side and attach the wheels.

Congratulations. You're done.

Btw is it square?
As we are going to drop reactangular panels in the rear ...


We've got a bottom shelf, a lower shelf, a top shelf, two workpanels and four doors. And a little panel for the Cameo box. Plus 12 hinges.
Slide the bottom shelf in. No need to fix it to the bottom frame: chiller and filter will hold it in place.
Shorten the front cassette feet and mount the cassette flush with the front. 4 parkers will do.

Prepare lower shelf: geleiders. Slide the lower shelf in. Bit tricky, but there is one corner that (just) slides around the riser.

Now slide the top shelf in. Easy. <need to fixate? because of compressor vibration?>

Bolt hinges to the frame, then to doors.
Same for both workpanels.
Align doors up or down in order to get flapped down workpanels horizontal

Mount both sideframes for the Cameo and add the little board. The hole is for that water tubes.

<what is left to do
cameo plankje
vinyl tube

en de banner, maar dat is een geval apart>
