Candle and Vase Holder

I started learning Onshape CAD and thought this would be an excellent model to try out.
It is based on a design by Eva Schildt called Constella. A candle and vase holder that lets you shape it the way you want (In a constellation, maybe?).

This design is infinitely expandible, with the image containing five cups, but it can be expanded to as many as you want.

If you want to use tea candles I can only recommend LED candles as they do not generate heat.

Instructions

For 3 candel/vase holders print:

3x cup
1x start_bar
1x bar
1x end_bar
1x start_bolt
3x bolt

For 5 candel/vase holders print:
5x cup
1x start_bar
3x bar
1x end_bar
1x start_bolt
5x bolt

For 10 candel/vase holders print:
10x cup
1x start_bar
8x bar
1x end_bar
1x start_bolt
10x bolt

Printing orientation

• I suggest you turn all the bars on their side for an easy print. Alternately right-sid-up with supports for a more consistent look from all angles. 
• Print the bolts with the round part facing up. A brim can be beneficial here for added bed adhesion. 
• The cups might need support for the first couple of layers. Alternately print them upside down with a brim or a raft if you feel conferrable bridging up to 37mm.

Assembly

Insert the start_bolt into the closed hole on the start_bar. For the rest of the bars, insert the bolts sandwiching two bars between the bolt and the cup. The end bar uses a regular bolt.

If you do not achieve a press-fit, add CA-glue, epoxy or hot melt glue to the bottom hole of the cup/start_bar. If you do this, ensure you do not fix the bars together as they need to rotate.

Dimensions

The cup has a diameter of 40mm, allowing a small vase or glass tube to fit inside. The cup is chamfered on the bottom, giving it a base diameter of 37mm, allowing a standard tea candle to fit snuggly. The hole and bolt have a built-in tolerance of .2mm.

Inserts

I will update this model with inserts for regular candles and a printable vase when I find some more time.
